What external changes are visible ‘after the last moult of a cockroach nymph?
Option A Mandibles become harder
Option B Anal cerci develop
Option C Both forewings and hindwings develop
Option D Labium develops

The correct answer is Option C Both forewings and hindwings develop.

This is because – The nymph develops into an adult after moulting 13 times. Wing pads are present in the next to last nymphal stage, but only adult cockroaches have both forewings and hindwings.
