C. pituitary
D. cerebral cortex

Explanation

To answer the question "Human body temperature is maintained by," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Homeostasis**:
- The human body maintains a stable internal environment, which includes regulating body temperature. This process is known as homeostasis.

2. **Identifying the Mechanism**:
- The specific mechanism that regulates body temperature is referred to as the thermostat mechanism or thermostat system.

3. **Locating the Control Center**:
- The thermostat system is located in a specific part of the brain known as the hypothalamus. The hypothalamus is a crucial component of the forebrain.

4. **Normal Body Temperature**:
- The hypothalamus helps maintain the body temperature around a set point, which is approximately 37 degrees Celsius (98.6 degrees Fahrenheit).

5. **Conclusion**:
- Therefore, the human body temperature is maintained by the hypothalamus.

### Final Answer:
The human body temperature is maintained by the hypothalamus.
