Cockroach exhibits gradual metamorphism, in the form of larva called the nymph, nymph do not have wings or reproductive structures. So, at every stage of development like , growth, formation of reproductive structures, formation of wings, it undergoes metamorphosis. At each stage it sheds its cuticle and a new layer of cuticle is formed, this is called moulting or ecdysis
So, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'
