B. Drinking; cutaneous transpiration and expired air: While drinking is indeed the main source of water intake, the greatest loss of water from the body is through urine, not cutaneous transpiration and expired air.

Correct Answer is D
Explanation
A. Penetrate the vagina: The acrosome does not play a role in penetrating the vagina. Its function is specifically related to the sperm's ability to penetrate the ovum, making this option incorrect.
B. Dissolve the stickiness of the semen: While enzymes do play a role in semen liquefaction, this is not the function of the acrosome. The acrosome is primarily involved in the process of fertilization, not semen modification.
C. Dissolve the mucosa of the uterus: The acrosome is not involved in dissolving the mucosa of the uterus. Its function is related to penetrating the barriers surrounding the ovum.
D. Penetrate barriers surrounding the ovum: The acrosome contains enzymes that break down the outer layers of the ovum (such as the zona pellucida), allowing the sperm to penetrate and fertilize the egg. This is the correct answer.
