Assertion : Water has a boiling point higher than that of `H_(2)S`.
Reason : At room temperature, water is liquid while `H_(2)S` is gas.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are False.

Explanation

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

**Assertion:** Water has a boiling point higher than that of H₂S.
**Reason:** At room temperature, water is liquid while H₂S is a gas.

### Step-by-Step Solution:

1. **Understanding the Assertion:**
- The boiling point of water (H₂O) is 100°C (at 1 atm pressure).
- The boiling point of hydrogen sulfide (H₂S) is -60.3°C (at 1 atm pressure).
- Therefore, the assertion that water has a boiling point higher than that of H₂S is **true**.

2. **Understanding the Reason:**
- At room temperature (approximately 25°C), water exists in the liquid state.
- Hydrogen sulfide (H₂S) exists as a gas at room temperature.
- Thus, the reason that at room temperature water is liquid while H₂S is a gas is also **true**.

3. **Evaluating the Relationship:**
- The reason provided explains why water remains liquid at room temperature while H₂S is a gas. This is primarily due to the presence of strong hydrogen bonding in water, which raises its boiling point compared to H₂S.
- Therefore, the reason is a correct explanation for the assertion.

4. **Conclusion:**
- Since both the assertion and reason are true, and the reason correctly explains the assertion, the answer is:
- **Option A:** Both assertion and reason are true, and the reason is the correct explanation for the assertion.

### Final Answer:
**Option A:** Both assertion and reason are true, and the reason is the correct explanation for the assertion.
