B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
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 analyze both the assertion and the reason provided.

### Step 1: Analyze the Assertion
The assertion states that "Ringworm disease is caused due to Roundworm."
- **Explanation**: Ringworm is not caused by roundworms. It is actually a fungal infection caused by fungi from the genera Microsporum, Trichophyton, and Epidermophyton. Roundworms, on the other hand, are a type of helminth (worm) that can cause diseases like ascariasis. Therefore, this assertion is **false**.

### Step 2: Analyze the Reason
The reason states that "Multiple lymph nodes are involved in ringworm."
- **Explanation**: Ringworm primarily affects the skin, scalp, and nails, and it does not typically involve lymph nodes. Lymph nodes are part of the immune system and may become involved in other types of infections, but not in ringworm. Thus, this reason is also **false**.

### Step 3: Conclusion
Since both the assertion and the reason are false, the correct answer is that both statements are incorrect.

### Final Answer
Both the assertion and the reason are false.
