The correct answer is A. Larva.
The silkworm is a moth whose larvae produce silk. The larvae are called silkworms, and they spin silk cocoons around themselves as they pupate. The silk from these cocoons is used to make silk fabric.
The silkworm’s life cycle begins with the egg. The eggs are laid by the adult moth, and they hatch into larvae. The larvae feed on mulberry leaves, and they grow rapidly. After about 40 days, the larvae spin silk cocoons around themselves. The larvae then pupate inside the cocoons, and they emerge as adult moths about 15 days later.
The silk from the silkworm’s cocoons is one of the strongest and most lustrous natural fibers. It has been used to make fabric for thousands of years. Silk is a popular choice for clothing, bedding, and other textiles.
Here is a brief description of each option:
- A. Larva: The larva is the stage of the silkworm’s life cycle in which it feeds and grows. The larvae are called silkworms, and they spin silk cocoons around themselves as they pupate.
- B. Egg: The egg is the stage of the silkworm’s life cycle in which it begins its development. The eggs are laid by the adult moth, and they hatch into larvae.
- C. Pupa: The pupa is the stage of the silkworm’s life cycle in which it transforms into an adult moth. The larvae spin silk cocoons around themselves, and they pupate inside the cocoons.
- D. Imago: The imago is the stage of the silkworm’s life cycle in which it is an adult moth. The adult moths emerge from the cocoons, mate, and lay eggs.
