Solution
The correct option is C Melatonin
- The pineal gland or pineal body (epiphysis or third eye) is a small endocrine gland.
- It secretes melatonin (hormone) which regulates the wake/sleep patterns and photoperiodic functions.
- Biorhythms or biological rhythms control sleep and wake cycles and other functions such as behaviour and endocrine rhythms. These functions are regulated by the circadian clock.
- The secretion of melatonin is triggered in dark and inhibited by light.
- So, the correct answer is 'Melatonin'.
