The correct option is A Prostate gland
The prostate gland is a single exocrine gland located between the bladder and penis in male mammals, which produces a large portion of the fluid, which makes up the semen when mixed with sperm. Whereas the gastric glands or fundic glands are found in the body, the gastric mucosa and fundus of the stomach (in all mammals), the mushroom shaped gland is not present in males and the inguinal canal is the passage in the abdominal wall present in both men and women.
Thus, the correct answer is option A.
