Camouflage -- they could reflect colors of the surroundings and break up the shape of the pupa; they might also look like dew droplets. Warning coloration. Filtering particular wavelengths of light which might be harmful to the monarchs.
These twelve tiny gold spots were believed to be ornamental only. The actual purpose of these tiny gold spots is to produce a hormone necessary for the butterfly's full development.
The telltale gold spots on the outside of a chrysalis are ports of entry for oxygen.
Ebright tried experiments on butterflies for a science fair. In his project, in the second year of high school, he tried to explain the purpose of twelve tiny gold spots on a Monarch pupa. He found out that those spots produced a hormone necessary for the full development of a butterfly.
Answer: Everyone believed that the twelve tiny gold spots were just ornamental ,the actual purpose of these tiny gold spots was to produce a hormone necessary for the butterfly's full development.
He tried to find the purpose of the twelve tiny gold spots on a monarch pupa. Along with another excellent science student, he built a device which showed that the spots were producing a hormone necessary for the butterfly's full development.

The second option which is 'b) secreted hormones' is correct as it can be referred from the text.
Studded in Gold
The fact that after the butterfly emerges from the chrysalis and the diadem appears yellow suggests that there's a pigment at play as well.
Richard's project on the purpose of the twelve tiny gold spots on a monarch pupa was highly valuable in two ways. List the two ways. Ebright's study of monarch pupas had a far reaching impact.
Solution : Richard raised thousands of butterflies, tagged them and released them to study their migration. But soon, he lost interest because only two of his tagged butterflies were returned to him and they had travelled only seventy-five miles.
The pupa (chrysalis) is stout (about 1.8 cm long) and shiny, reflecting silver to gold. Chrysalis (pupa) of Common Crow or Oleander Butterfly, Euploea core.
What happens inside a chrysalis or cocoon? First, the caterpillar digests itself, releasing enzymes to dissolve all of its tissues. If you were to cut open a cocoon or chrysalis at just the right time, caterpillar soup would ooze out.
The new chrysalis is soft and easily deformed for the first hour after pupating. Anything that touches the soft chrysalis can cause damage. Some damage is natural, caused by twigs or leaves surrounding the soft chrysalis.
During pupation, larval structures break down, and adult structures such as wings appear for the first time. The adult emerges by either splitting the pupal skin, chewing its way out, or secreting a fluid that softens the silk cocoon (if present). The process of pupation is controlled by hormones.
The purpose of tagging monarchs is to associate the location of original capture with the point of recovery for each butterfly. The data from these recaptures are used to determine the pathways taken by migrating monarchs, the influence of weather on the migration, the survival rate of the monarchs.
Right now, the internet is obsessing over this video of a butterfly pupae that looks like gold when you set your eyes on it. However, 'not everything that glitters is gold' stands true here. The pupae actually belongs to a species of butterfly named cream-spotted tigerwing.
These shiny, metallic-looking chrysalises are thought to help protect the growing butterfly by fooling potential predators. The shiny chrysalises might look like water droplets on leaves. Or, they just might be so shiny that they reflect their surrounding areas like a mirror.
As a chrysalis, Monarchs and Queens could be twins, except that Queens are slightly smaller. Both attach themselves vertically from a a horizontal surface with a silk button after forming a “J” shape, then spin a shiny green chrysalis flecked with gold dots.
A Monarch chrysalis just moments before the adult butterfly emerges. Starting a few hours prior to its emergence, also known as “eclosure,” the green and gold cuticle of the pupa becomes ever more transparent, exposing the colors of the wings.
They are not metallic (so they aren't really gold), but the cells reflect light like metals do, giving them the appearance of being metallic. Other danaids have silver, copper, or gold spots.
The Golden Cocoon is a 1925 American silent drama film directed by Millard Webb and written by Louis D. Lighton, and Hope Loring. It is based on the 1924 novel The Golden Cocoon by Ruth Cross. The film stars Huntley Gordon, Helene Chadwick, Richard Tucker, Frank Campeau, Margaret Seddon, and Carrie Clark Ward.
What's that red stuff? Butterflies excrete a red liquid which is sometimes mistaken for blood when in reality it is actually meconium, "pupal fluid" which isn't blood at all. It is made up of waste material that is produced during the pupal stage.
These spots are scent glands that help males attract female mates. Females have thicker wing veins than males. The butterfly's body is black with white markings. Monarch caterpillars are striped with yellow, black, and white bands, and reach lengths of two inches (five centimeters) before metamorphosis.
The metamorphosis from a caterpillar into a butterfly occurs during the pupa stage. During this stage, the caterpillar's old body dies and a new body forms inside a protective shell known as a chrysalis.
How much was the necklace actually worth Class 10? As Mme Forestier tells Matilda at the end of the story, the necklace was only worth 500 francs while she and her husband thought that it was a real one which was 40,000 Francs.
