Answer 2

The correct option is c) pupa.

Explanation:

• During the pupa process, the silkworm creates a net to hold itself together. Then it swings its head and spins a protein-based thread into silk.
• The silkworm's life cycle begins with an egg. The egg is laid by a female moth, which is often the size of a single dot.
• Silkworms use this mechanism to create a protective cocoon around themselves. It's about the size of a small cotton ball and is constructed out of a single silk thread.
• The pupa phase is characterised by a lack of movement. At this moment, the pupa is destroyed by putting the cocoon into a boiling state.
