Solution

The correct option is A Hind wings are protective and are not useful in flight
The first pair of wings arises from mesothorax and the second pair from metathorax. Forewings called tegmina are opaque dark and leathery and cover the hind wings when at rest. The hind wings are transparent, membranous and are used in flight.
So the correct answer is 'Hind wings are protective and are not useful in flight'.
