C. Statement -1 is True Statement -2 is False
D. Statement -1 is False Statement -2 is True

Explanation

To solve the question, we need to analyze both statements regarding phenol and benzoic acid in relation to their behavior with sodium bicarbonate (NaHCO₃).

### Step-by-Step Solution:

1. **Understanding the Reactivity of Benzoic Acid:**
- Benzoic acid (C₆H₅COOH) is a carboxylic acid and is known to be a stronger acid compared to phenol.
- When benzoic acid reacts with sodium bicarbonate, it can donate a proton (H⁺) to form sodium benzoate and carbonic acid (H₂CO₃), which decomposes to release carbon dioxide (CO₂) gas.
- Reaction:
\[ C_6H_5COOH + NaHCO_3 \rightarrow C_6H_5COONa + H_2O + CO_2 \uparrow \]

2. **Understanding the Reactivity of Phenol:**
- Phenol (C₆H₅OH) is a weaker acid compared to benzoic acid. It does not readily donate a proton to sodium bicarbonate.
- Therefore, phenol does not react with sodium bicarbonate, and no gas is released when phenol is treated with NaHCO₃.

3. **Evaluating Statement 1:**
- Statement 1 claims that phenol and benzoic acid can be distinguished by NaHCO₃. This is true because only benzoic acid will react and release CO₂ gas, while phenol will not react.
- Conclusion: **Statement 1 is true.**

4. **Evaluating Statement 2:**
- Statement 2 claims that phenol releases CO₂ gas from NaHCO₃. This is false because phenol does not react with NaHCO₃ and hence does not release any gas.
- Conclusion: **Statement 2 is false.**

### Final Conclusion:
- Statement 1 is true, and Statement 2 is false.
