Answer 1

The Correct Option is D

Step 1: Understanding the function of the glands. 
- The Hypothalamus is located in the brain and regulates many bodily functions, including hormone release. 
- The Pineal gland is also located in the brain and is responsible for regulating sleep-wake cycles by releasing melatonin. 
Step 2: Analyzing the options. 
- Option (A) includes Parathyroid, which is not located in the brain, so it is incorrect. 
- Option (B) includes Thymus, which is located in the chest, not the brain, so it is incorrect. 
- Option (C) includes Thymus again, so it is also incorrect. 
- Option (D) is correct, as both the Hypothalamus and Pineal gland are located in the brain.
