The correct option is A Conglobate gland
Jointed appendages and paired antennae are present in both sexes.
Anal cerci are a pair of appendages at the end of the abdomen arising from the 10th segment of the body of the cockroaches in both sexes, males and females.
Conglobate glands are present in the male cockroach. It is a large elongate sac-like structure, lies beneath the mushroom gland and ejaculatory duct. It opens by the side of the male gonopore.
