B. Pineal gland
C. Thymus gland
D. Adrenal glands

The correct answer is (B) Pineal gland.
The pineal gland is a small, pea-shaped gland located in the brain. It is an important part of the endocrine system, which is responsible for producing and regulating hormones within the body. One of the primary hormones produced by the pineal gland is melatonin.
Melatonin is a hormone that plays a key role in managing sleep-wake cycles, commonly known as circadian rhythms. The production of melatonin is influenced by the light-dark cycle; it typically increases during the evening and at night when it is dark, and decreases during the day when it is light. This pattern helps regulate when you feel sleepy or awake, thereby coordinating your sleep patterns.
In summary, the pineal gland's ability to secrete melatonin is crucial for regulating sleep patterns, making it an essential component of maintaining proper sleep health.
