C	melatonin, circadian

Explanation:

Detailed explanation-1: -Melatonin is a natural hormone that’s mainly produced by your pineal gland in your brain. It plays a role in managing your sleep-wake cycle and circadian rhythm. Scientists still have a lot to learn about all of its effects on the human body.

Detailed explanation-2: -Melatonin plays an important role in regulating human sleep. Administration of sustained-release or transdermal formulation melatonin reduces sleep latency, increases total sleep time, and improves sleep maintenance [12, 13].

Detailed explanation-3: -Darkness prompts the pineal gland to start producing melatonin while light causes that production to stop. As a result, melatonin helps regulate the circadian rhythm and synchronize the sleep-wake cycle with night and day.
