Assertion : In Monera kingdom, cell wall bears unique polymers of amino sugars and amino acids called peptidoglycans.
Reason : It is a derivative of phospholipids.

Options

A. If both Assertion and Reason are true and the Reason is a correct explanation of the Assertion.
B. If both Assertion and Reason are true but Reason is not a correct explantion of the Assertion.
C. If Assertion is true but the Reason is false.
D. If both Assertion and Reason are false.

Answer

To solve the question regarding the assertion and reason about the Monera kingdom and peptidoglycans, we can break it down step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that in the Monera kingdom, the cell wall contains unique polymers of amino sugars and amino acids known as peptidoglycans.
- This statement is true. Peptidoglycans are indeed a major component of the bacterial cell wall and consist of sugars (like N-acetylglucosamine and N-acetylmuramic acid) linked with amino acids.

2. **Understanding the Reason**:
- The reason given is that peptidoglycans are derivatives of phospholipids.
- This statement is false. Peptidoglycans are not derived from phospholipids; they are composed of sugars and amino acids, as mentioned earlier.

3. **Evaluating the Relationship**:
- Since the assertion is true and the reason is false, we need to determine the correct option based on this evaluation.

4. **Conclusion**:
- The correct answer is that the assertion is true, but the reason is false. Therefore, the answer is option 3.

### Final Answer:
- The assertion is true, but the reason is false (Option 3).
