D. Kidney functions

Answer

**Step-by-Step Solution:**

1. **Understanding the Pineal Gland**: The pineal gland is a small endocrine gland located in the brain, specifically on the dorsal side of the forebrain. It is primarily known for its role in the production of the hormone melatonin.

3. **Effects on Body Functions**: The pineal gland and melatonin influence several body functions:
- **Body Temperature**: Melatonin plays a role in regulating body temperature during sleep.
- **Defense Capability**: Melatonin is also thought to influence the immune system and defense mechanisms.
- **Metabolism**: It has been linked to metabolic processes and energy balance.

4. **Identifying the Irrelevant Function**: The question asks which function is NOT related to the pineal gland. The options provided are:
- Body Temperature
- Defense Capability
- Metabolism
- Kidney Function

5. **Analyzing Each Option**:
- Body Temperature: Related to the pineal gland through melatonin regulation.
- Defense Capability: Also related as melatonin can influence immune responses.
- Metabolism: Linked to the effects of melatonin on metabolic processes.
- Kidney Function: There is no direct relation of the pineal gland or melatonin with kidney function.

6. **Conclusion**: The pineal gland is not related to kidney function. Therefore, the correct answer is option 4.

**Final Answer**: The pineal gland is not related to kidney function.
