Explanation:

Melatonin is a hormone that regulates sleep - wake cycles. It is secreted by the pineal gland, not the pituitary gland (so option D is incorrect). Exposure to light decreases melatonin production (so option C is incorrect). Melatonin helps in inducing sleep and can quicken the process of falling asleep (so option B is correct). It does affect feelings of drowsiness (so option A is incorrect).

Answer:

B. It can quicken the process of falling asleep
