The correct answer is C. Male cockroach.

Explanation: The conglobate glands are specialized glands that are found in the reproductive system of the male cockroach. These glands are involved in producing secretions that play a role in the reproductive process, particularly in the formation of the spermatophore, which is important for fertilization.

Here's a breakdown of the options:

A. Earthworm: Earthworms have different reproductive structures, such as testes and ovaries, but do not possess conglobate glands.
B. Housefly: Houseflies also have reproductive systems, but they do not have conglobate glands.
C. Male cockroach: The male cockroach has conglobate glands, which are responsible for secreting substances that help in mating.
D. Female cockroach: The female cockroach does not have conglobate glands; instead, it has other reproductive organs like ovaries and a spermatheca for storing sperm.
Thus, the conglobate gland is found in the reproductive organs of the male cockroach.
