The correct option is B Overproduction of adrenal androgens

The hormones responsible for the development of male characteristics are androgens. Androgens are sexocorticoids secreted from adrenal cortex. Two types of androgens are found in males, testosterone and androstenedione. A little amount of androgens are secreted in females also but sometimes due to hormonal imbalance, adrenal cortex starts producing more androgens in female due to which some male characters like facial hair develop in females.

So, the correct answer is 'Overproduction of adrenal androgens'.
