Assertion (A): Smooth endoplasmic reticulum is associated with synthesis of lipids.
Reason (R): Smooth endoplasmic reticulum possesses ribosomes.

Options

A. Both Assertion and Reason are true and Reason is the correct explanation for Assertion.
B. Both Assertion and Reason are true but Reason is not the correct explanation for Assertion.
C. Assertion is true and Reason is false.
D. Assertion is false and Reason is true.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Assertion (A)**: The assertion states that "Smooth endoplasmic reticulum is associated with the synthesis of lipids." This is true because the smooth endoplasmic reticulum (SER) is primarily involved in the synthesis of lipids, which includes fats, phospholipids, and steroids.

2. **Understanding the Reason (R)**: The reason provided is "Smooth endoplasmic reticulum possesses ribosomes." This statement is incorrect. The smooth endoplasmic reticulum does not have ribosomes on its surface. Ribosomes are found on the rough endoplasmic reticulum (RER), which is why it is termed "rough."

3. **Conclusion**: Since the assertion is true and the reason is false, we conclude that the correct relationship between the assertion and reason is that the assertion is correct, but the reason is incorrect.
