Answer 1

The correct option is B It will moult into pupa

If juvenile hormone is absent when silkworm moults. It will moult into pupa.

In insects, Juvenile hormone refers to a group of hormones, which ensure growth of the larva, while preventing metamorphosis. Because of their rigid exoskeleton, insects grown in their development by successively shedding their exoskeleton(a process known as molting).
