Assertion : The drop of a liquid is always spherical or nearly spherical.
Reason : Water is not a viscous liquid.

Options

A. If both Assertion and Reason are CORRECT and Reason is the CORRECT explanation of the Assertion.
B. If both Assertion and Reason are CORRECT but Reason is not the CORRECT explanation of the Assertion.
C. If Assertion is CORRECT but Reason is INCORRECT.
D. If Assertion is INCORRECT but Reason is CORRECT.

Explanation

To solve the question, we need to analyze both the assertion and the reason provided.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "The drop of a liquid is always spherical or nearly spherical." This is a correct statement. The shape of a liquid drop is influenced by surface tension, which causes the liquid to minimize its surface area. A sphere has the smallest surface area for a given volume, which is why liquid droplets tend to be spherical.

**Hint**: Think about why liquids minimize their surface area. What physical property causes this behavior?

2. **Understanding the Reason**:
- The reason provided is "Water is not a viscous liquid." This statement is misleading. While water has low viscosity compared to many other liquids, it is not correct to say that it is "not a viscous liquid" at all. Viscosity refers to a liquid's resistance to flow, and water does have some viscosity, albeit low.

**Hint**: Consider the definition of viscosity. What does it mean for a liquid to be viscous, and how does water compare to other liquids?

3. **Analyzing the Relationship**:
- The assertion is correct, but the reason is incorrect. The spherical shape of a liquid drop is due to surface tension and cohesive forces among the molecules, not solely because of the viscosity of the liquid. Therefore, the reason does not support the assertion.

**Hint**: Evaluate whether the reason logically supports the assertion. Does the viscosity of water affect the shape of its droplets?

4. **Conclusion**:
- Since the assertion is true and the reason is false, the correct answer to the question is that the assertion is correct, but the reason is incorrect.

**Final Answer**: Assertion is correct; Reason is incorrect.

### Summary of the Solution:
- The assertion about the shape of liquid drops is true due to surface tension.
- The reason regarding water's viscosity is misleading as water does have viscosity, albeit low.
- Therefore, the assertion stands true while the reason does not support it.
