Cockroaches indeed undergo numerous moltings during their developmental stages, which supports the assertion. Molting is a crucial part of their growth process, allowing them to shed their old exoskeleton and develop a new one as they go through successive stages of growth.

On the other hand, the reason provided, stating that cockroaches exhibit gradual metamorphosis, is not the correct explanation for the assertion. Cockroaches undergo incomplete metamorphosis. In incomplete metamorphosis, the immature nymphs resemble miniature versions of the adult cockroaches and undergo molting to grow and develop into adulthood. This process differs from gradual metamorphosis which involves more significant changes in form and structure between the immature and adult stages.

Therefore, both the assertion and reason are true but the reason is not the correct explanation of the assertion.
Hence, option 2 is the correct answer.
