Assertion : Small water drops are sperical while bigger water drops are not.
Reason : In small water drops surface tension forces dominate while in bigger water drops gravity forces dominate.

Options

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

Explanation

To solve the question regarding the assertion and reason, we will analyze both statements step by step.

### Step 1: Understand the Assertion
The assertion states that "Small water drops are spherical while bigger water drops are not."

- **Explanation**: Small water droplets tend to take a spherical shape due to the dominance of surface tension. Surface tension acts to minimize the surface area of the droplet, leading to a spherical shape, which has the least surface area for a given volume.

### Step 2: Understand the Reason
The reason states that "In small water drops, surface tension forces dominate while in bigger water drops, gravity forces dominate."

- **Explanation**: For small droplets, the effect of surface tension is much greater than the effect of gravity. As the size of the droplet increases, the gravitational force (which is proportional to the volume of the droplet) becomes significant compared to the surface tension (which is proportional to the surface area).

### Step 3: Analyze the Relationship Between Assertion and Reason
- The assertion is correct because small water drops are indeed spherical due to surface tension.
- The reason is also correct because it explains why small drops maintain a spherical shape (due to surface tension) while larger drops may not (as gravity starts to dominate).

### Step 4: Conclusion
Both the assertion and the reason are correct, and the reason correctly explains the assertion. Therefore, the correct option is:

**Assertion and Reason are both correct, and Reason is the correct explanation of Assertion.**

### Final Answer
The correct answer is Option A: Both assertion and reasoning are correct, and reasoning is the correct explanation of assertion.
