C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are false.

Answer

To solve the question, we need to evaluate the assertion and the reason provided:

**Assertion:** Visceral muscles do not exhibit any striation and are smooth in appearance.
**Reason:** Their activities are not under the voluntary control of the nervous system.

### Step-by-Step Solution:

1. **Understanding the Assertion:**
- Visceral muscles are also known as smooth muscles. They are found in the walls of internal organs (viscera) such as the stomach, intestines, and blood vessels.
- Smooth muscles do not have striations, which means they appear smooth under a microscope. This characteristic is true.

2. **Understanding the Reason:**
- The reason states that the activities of visceral muscles are not under voluntary control, which is also correct.
- Smooth muscles operate involuntarily, meaning they function without conscious control. This is true for visceral muscles.

3. **Evaluating the Relationship:**
- While both the assertion and the reason are true, the reason does not explain why visceral muscles are smooth. The smooth appearance is due to the absence of striations, not directly because they are under involuntary control.
- Therefore, the reason does not provide a correct explanation for the assertion.

4. **Conclusion:**
- Since both the assertion and the reason are true, but the reason does not explain the assertion, the correct answer is (b): If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.

### Final Answer:
(b) If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
