Which of the following is mismatched ?

Options

A. Cerebrum - Memory
B. Olfactory lobes - Sense of smell
C. Cerebellum - Equilibrium of body
D. Medulla oblongata - Temperature regulation

Answer

To solve the question "Which of the following is mismatched?" we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Cerebrum - Memory**:
- The cerebrum is indeed responsible for memory. Specifically, the temporal lobe of the cerebrum plays a key role in the formation and retrieval of memories.
- **Conclusion**: This pairing is correct.

2. **Olfactory Lobe - Sense of Smell**:
- The olfactory lobes are responsible for the sense of smell. They process olfactory information received from the nasal cavity.
- **Conclusion**: This pairing is correct.

3. **Cerebellum - Equilibrium of Body**:
- The cerebellum is responsible for maintaining balance and posture, which is crucial for the equilibrium of the body. It integrates sensory information from the vestibular system and proprioceptors.
- **Conclusion**: This pairing is correct.

4. **Medulla Oblongata - Temperature Regulation**:
- The medulla oblongata is responsible for autonomic functions such as breathing, heart rate regulation, and blood pressure control. However, it does not regulate body temperature.
- **Conclusion**: This pairing is incorrect.

### Final Answer:
The mismatched option is **Medulla Oblongata - Temperature Regulation**.
