Correct Answer:

Male Cockroach

Solution : The correct option is male cockroach.

The "conglobate gland" is a male cockroach structure. In male cockroaches, the conglobate gland is a specialised gland connected with the reproductive system. It's termed a "conglobate" structure because it looks like a folded leaf. This gland creates and stores specific substances that are important in male cockroach mating behaviour. Male cockroaches may produce these glandular fluids during courting as part of their reproductive displays or to attract females.
