The prostate gland is described in all of the following ways except:
a. produces acid phosphatase to break apart semen and release spermatozoa in the vagina.
b. produces an antibiotic substance that kills bacteria in the vagina.
c. produces a substance that activates enzymes in the spermatozoon head so that it can penetrate the ovum.
d. is part of the urinary system as well as the reproductive system

The correct answer will be option- D.

Explanation:

The prostate gland is a walnut-shaped gland present between the bladder and penis.

The prostate gland is a part of the reproductive system and not the urinary system as it helps in the nourishment and protection of the sperm cells. It secretes a fluid which contains enzymes like phosphatases, lytic enzymes and antibiotics which helps in the protection and passage of sperm to the egg cell.

Thus, option- D is the correct answer.
