A. Motor
B. Sensory
C. Motor and sensory
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Facial Nerve**: The facial nerve, also known as cranial nerve VII, is a crucial component of the nervous system. It is responsible for various functions including facial expressions and taste sensations.

2. **Analyzing the Options**:
- **Option 1: Motor Nerve**: This option suggests that the facial nerve is solely a motor nerve. However, this is incorrect because the facial nerve also has sensory functions.
- **Option 2: Sensory Nerve**: This option claims that the facial nerve is only a sensory nerve. This is also incorrect as the facial nerve has motor functions as well.
- **Option 3: Motor and Sensory (Mixed Nerve)**: This option states that the facial nerve is a mixed nerve, which means it has both motor and sensory functions. This is the correct answer as the facial nerve controls muscles for facial expression and conveys taste sensations from the anterior two-thirds of the tongue.
- **Option 4: None of These**: This option implies that none of the previous options are correct. Since we have established that option 3 is correct, this option is also incorrect.

3. **Conclusion**: After analyzing all options, the correct answer is that the facial nerve is a mixed nerve (motor and sensory).

**Final Answer**: The facial nerve is a mixed nerve (motor and sensory).
