Solution

The correct option is B Both forewings and hind wings develop
Nymph is the immature form in the life cycle of several arthropods.

In cockroaches, the nymph grows by undergoing moulting for about 13 times and then becomes an adult. The nymphal stage before the adult stage has wing pads, which develops into wings in the case of adult cockroaches.

Anal cerci are found at the posterior end of abdomen and are able to detect vibrations.

Labium and mandibles are mouthparts in cockroaches.
