Assertion `:-` Smallest blood cell is RBC
Reason `:-` Platelets are cell fragments not true cells.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertiion.
C. If Assertion is False but the Reason is True.
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: "Smallest blood cell is RBC (Red Blood Cell)."

- **Fact Check**: Red Blood Cells (RBCs) are indeed one of the smallest cells in the blood, but they are not the smallest. The smallest blood components are actually platelets, which are cell fragments.

### Step 2: Analyze the Reason
The reason states: "Platelets are cell fragments, not true cells."

- **Fact Check**: This statement is correct. Platelets are derived from the fragmentation of megakaryocytes in the bone marrow and do not have a complete cell structure like RBCs or white blood cells.

### Step 3: Conclusion
- Since the assertion is false (the smallest blood cells are platelets, not RBCs) and the reason is true (platelets are indeed cell fragments), we can conclude that the assertion does not support the reason.

### Final Answer
The correct option is that the assertion is false, but the reason is true.
