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

Answer

To solve the question regarding the assertion and reason about Rudolf Virchow, we can break it down step by step:

### Step 1: Understand the Assertion
The assertion states that "Rudolf Virchow was the pioneer scientist to modify Schleiden and Schwann's hypothesis."
- **Explanation**: This is true. Rudolf Virchow is known for his contributions to cell theory, particularly for adding the idea that all cells arise from pre-existing cells, which modified the earlier ideas proposed by Schleiden and Schwann.

### Step 2: Understand the Reason
The reason states that "Rudolf Virchow proposed about cell lineage."
- **Explanation**: This is also true. Virchow's statement that "Omnis cellula e cellula" (all cells come from cells) emphasizes the lineage aspect of cells, indicating that new cells are derived from existing ones.

### Step 3: Evaluate the Relationship Between Assertion and Reason
Now we need to determine if the reason provided is a correct explanation of the assertion.
- **Explanation**: While both the assertion and reason are true, the reason does not directly explain the assertion. The assertion is about modifying the hypothesis, while the reason discusses cell lineage.

### Step 4: Choose the Correct Option
Based on the evaluation:
- **Option 1**: Both assertion and reason are true, and reason is the correct explanation of assertion. (Incorrect)
- **Option 2**: Both assertion and reason are true, but reason is not the correct explanation of assertion. (Correct)
- **Option 3**: Assertion is true, but reason is false. (Incorrect)
- **Option 4**: Both assertion and reason are false. (Incorrect)

### Final Answer
The correct answer is **Option 2**: Both assertion and reason are true, but reason is not the correct explanation of assertion.
