Assertion :- Water in liquid state is more stable than ice at room temperature.
Reason :- Water in liquid from has higher entropy than ice.

Options

A. if both Assertion and Reason are true and reason is the correct explanation of the assertion.
B. if both assertion and reason are true but reason is not the correct expalanation of the assertion
C. if assertion is true, reason is false
D. both assertion and reason are false statements.

Explanation

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

**Assertion:** Water in liquid state is more stable than ice at room temperature.

**Reason:** Water in liquid form has higher entropy than ice.

### Step-by-Step Solution:

1. **Understanding the Assertion:**
- At room temperature (approximately 25°C), water exists primarily in its liquid state. Ice, which is the solid form of water, tends to melt at this temperature.
- Since ice melts to form liquid water at room temperature, we can conclude that liquid water is more stable than ice under these conditions.
- Therefore, the assertion is **true**.

2. **Understanding the Reason:**
- Entropy is a measure of disorder or randomness in a system. The higher the entropy, the more disordered the system is.
- In general, the solid state (like ice) has lower entropy compared to the liquid state (like water) because the molecules in a solid are more ordered than those in a liquid.
- Thus, liquid water has higher entropy than ice, which supports the reason provided.
- Therefore, the reason is also **true**.

3. **Connecting the Assertion and Reason:**
- The reason explains why the assertion is true. The higher entropy of liquid water compared to ice indicates that liquid water is more stable at room temperature.
- Hence, the reason provides a correct explanation for the assertion.

4. **Conclusion:**
- Both the assertion and the reason are true, and the reason correctly explains the assertion.

### Final Answer:
- The correct option is: **Both assertion and reason are true and reason is the correct explanation of assertion.**
