Final Answer :
A
Explanation :
Testosterone is the primary male sex hormone that is responsible for the development and maintenance of secondary sexual characteristics in males. These include the growth of facial and body hair, deepening of the voice, increased muscle mass, and development of the male reproductive system. Estrogen, FSH, LH, and progesterone are all hormones that are involved in various aspects of reproductive physiology, but they do not play as direct a role in the maintenance of male secondary sexual characteristics as testosterone does.
