Solution
The correct option is D Phallic gland
In male cockroaches, the sperm are produced by the testes and are temporarily stored in the seminal vesicles, where they are covered by the secretions of the utriculi breviores and utriculi majors (mushroom gland). The layers formed by these glands are slimy.
Phallic gland is also called a conglobate gland. The phallic gland’s secretion creates a hard external layer on the outer surface of the spermatophores.
Collateral glands are associated with the female reproductive system of cockroach.
