Statement I: Finer the capillary, greater is the height to which the liquid rises in the tube
Statement II: This is in accordance with the ascent formula.

Options

A. Statement I is true, statement II is true and Statement II is a correct explanation for Statement I.
B. Statement I is true, Statement II is true and Statement II is NOT the correct explanation for Statement I.
C. Statement I is true, Statement II is false.
D. Statement I is false, Statement II is true.

Explanation

To analyze the given statements, we need to understand the concepts of capillary action and the ascent formula.

### Step-by-Step Solution:

1. **Understanding Statement I**:
- Statement I claims that "Finer the capillary, greater is the height to which the liquid rises in the tube."
- This means that if we have a capillary tube with a smaller radius (finer), the liquid will rise to a greater height compared to a capillary tube with a larger radius.

2. **Understanding Statement II**:
- Statement II states that "This is in accordance with the ascent formula."
- The ascent formula for capillary action is given by:
\[ h = \frac{2s \cos \theta}{r \rho g} \]
- Here, \( h \) is the height to which the liquid rises, \( s \) is the surface tension of the liquid, \( \theta \) is the contact angle, \( r \) is the radius of the capillary tube, \( \rho \) is the density of the liquid, and \( g \) is the acceleration due to gravity.

3. **Analyzing the Ascent Formula**:
- From the ascent formula, we can see that the height \( h \) is inversely proportional to the radius \( r \) of the capillary tube. This means:
\[ h \propto \frac{1}{r} \]
- Therefore, if the radius \( r \) decreases (the capillary tube becomes finer), the height \( h \) increases. This confirms Statement I.

4. **Conclusion**:
- Since Statement I is true (finer capillary leads to greater height) and Statement II correctly explains why this is the case (due to the ascent formula), both statements are true.
- Thus, the correct conclusion is that both statements are true and Statement II is the correct explanation for Statement I.

### Final Answer:
Both Statement I and Statement II are true, and Statement II is the correct explanation for Statement I.
