Larvae
Cocoon
Larvae and adult moth
Adult moth

Answer 1

We obtain silk, which is an important commercial product from an organism called silkworm. Bombyx, also called the silkworm, belongs to the phylum Arthropoda. The process of maintaining silkworms in-order to obtain silk from them is called sericulture.

Complete step by step answer: Silk is an example of natural fiber and is used in the textile industry on a large scale. The larvae of the silkworm produce a structure around it called a cocoon. It is produced in order to protect themselves from predators. Silk is obtained in these cocoons. Cocoons are seen as a white structure seen around these larvae, in which the larvae further develop into the pupa stage. We know that Bombyx mori is the name of species of silkworm that is widely used for silk production from the cocoon produced by its larvae.
We know that the process of extracting silk from the cocoons is an important process in sericulture. Cocoons are baked, boiled, or heated in order to get the contents needed for silk manufacture
When the cocoon is kept in boiled water, all the binding components that bind the thread of the cocoon will dissolve away. In this way, we extract the cocoon fiber by the process of boiling. It can also be done in some other ways.
After obtaining the silk thread from the cocoon, it is dyed into various colors. It also contains several other steps like spinning, weaving, printing, etc.
Hence the correct option is B.

Note: Larvae of silkworm are also called caterpillars. These mainly feed on mulberry leaves in order to grow. Keep in mind that although the silk threads look thin, they are strong and don’t break easily.
