Melatonin is a hormone that is primarily involved in regulating daily biological rhythms and sleep in humans.

Melatonin levels rise in the evening and stay high throughout the night, helping us to fall asleep and stay asleep. Therefore, the best choice is A, daily biological rhythms and sleep. The other options - B, response to drugs; C, response to fight or flight situations; and D, physical changes in girls at puberty - are not primary roles of melatonin.
