Assertion :- Primary wall is capable of growth.
Reason:- It diminishes as cell matures.

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 Assertion.
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 provided, we will analyze each statement step by step.

### Step 1: Analyze the Assertion
- **Assertion**: "Primary wall is capable of growth."
- The primary wall is indeed a thin and flexible layer of the cell wall found in growing cells. It allows for cell expansion and growth. Therefore, this assertion is **true**.

### Step 2: Analyze the Reason
- **Reason**: "It diminishes as the cell matures."
- As cells mature, they often undergo changes that can lead to the thickening or modification of the cell wall. In many cases, the primary wall may be replaced or supplemented by a secondary wall, which is thicker and more rigid. However, the primary wall itself does not literally diminish in size; rather, it may be modified. Thus, this reason is **true**, but it does not correctly explain the assertion.

### Step 3: Determine the Relationship Between Assertion and Reason
- The assertion is true, and the reason is also true, but the reason does not provide a correct explanation for the assertion. The primary wall's capability for growth is not directly linked to its diminishing nature as the cell matures.

### Step 4: Choose the Correct Option
- Based on the analysis:
- Both assertion and reason are true.
- The reason is not the correct explanation of the assertion.
- Therefore, the correct answer is: **Both assertion and reason are true, but reason is not the correct explanation of assertion.**

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