D. If both Assertion & Reason are False

Explanation

To solve the question, we need to analyze both the assertion and the reason provided.

### Step-by-Step Solution:

1. **Analyze the Assertion:**
- The assertion states that "Plasma cells of connective tissue proper are called as cartwheel cells."
- Plasma cells are indeed a type of white blood cell that produces antibodies. They have a characteristic appearance under a microscope that resembles a cartwheel due to their arrangement of the nucleus and cytoplasm.
- Therefore, this assertion is **true**.

2. **Analyze the Reason:**
- The reason states that "Lymphocyte cell is the largest cell of connective tissue proper."
- Lymphocytes, which include B-cells and T-cells, are actually among the smaller cells in connective tissue. They are not the largest; rather, cells like macrophages or fibroblasts can be larger.
- Therefore, this reason is **false**.

3. **Conclusion:**
- Since the assertion is true and the reason is false, we can conclude that the correct answer to the question is that the assertion is true, but the reason is false.

### Final Answer:
The correct answer is: **C - Assertion is true, but reason is false.**
