Explanation:

Acne is primarily caused by hormonal changes (especially during puberty, menstruation, etc.), which influence sebum production. A strict diet (A) and eating at night (B) are not primary causes. Dry skin (D) is unrelated; acne is more associated with oily skin and blocked pores due to hormonal factors. So the correct answer is C.

Answer:

C. hormones
