Assertion (A) Liquids tend to have maximum number of molecules at their surface.
Reason (R) Small liquid drops have spherical shape.

Options

A. Both A and R are true and R is the correct explanation of A
B. Both A and R are true but R is not the correct explanation of A
C. A is true but R is false
D. A is false but R is true

Explanation

To analyze the given assertion and reason, we will break down the statements and evaluate their validity step by step.

### Step 1: Evaluate the Assertion
**Assertion (A):** "Liquids tend to have maximum number of molecules at their surface."

- This statement is **false**. In liquids, the molecules are more densely packed in the bulk of the liquid compared to the surface. The surface molecules are fewer in number because they are not surrounded by other liquid molecules on all sides, unlike those in the interior.

### Step 2: Evaluate the Reason
**Reason (R):** "Small liquid drops have spherical shape."

- This statement is **true**. Small liquid drops do take on a spherical shape due to surface tension. Surface tension is the property of liquids that causes them to minimize their surface area. A sphere has the least surface area for a given volume, which is why small drops form into this shape.

### Step 3: Conclusion
- Since the assertion is **false** and the reason is **true**, we can conclude that the correct relationship is that the assertion does not support the reason. Therefore, the correct option would be that the assertion is false and the reason is true.

### Final Answer
- The assertion is false, and the reason is true. Thus, the correct option is **D**.
