Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
A pair of branched colleterial glands are present behind the ovary in female cockroaches. These glands open into the genital pouch separately, just above the spermathecal aperture and their secretion forms a hard egg case around the eggs called Ootheca.
The development of cockroach is hemimetabolous because there's no pupal stage in the transition from larva to adult.
So, the correct option is 'Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'.
