C. water is stronger acid than phenol
D. None of these

Answer

To solve the given reaction and understand what it suggests, we can break it down step by step.

### Step 1: Identify the Reactants and Products
The reaction given is:
\[ C_{6}H_{5}ONa + CO_{2} + H_{2}O \rightarrow C_{6}H_{5}OH + NaHCO_{3} \]

Here, the reactants are sodium phenoxide (\( C_{6}H_{5}ONa \)), carbon dioxide (\( CO_{2} \)), and water (\( H_{2}O \)). The products are phenol (\( C_{6}H_{5}OH \)) and sodium bicarbonate (\( NaHCO_{3} \)).

### Step 2: Analyze the Reaction
In this reaction, sodium phenoxide reacts with carbon dioxide and water to produce phenol and sodium bicarbonate. The key point here is the involvement of carbon dioxide and water, which can form carbonic acid (\( H_{2}CO_{3} \)) in solution.

### Step 3: Understand the Acidity
Carbonic acid is a weak acid that can dissociate to form bicarbonate ions (\( HCO_{3}^{-} \)). The reaction suggests that carbonic acid is a stronger acid than phenol.

### Step 4: Compare the Acidity
To understand why carbonic acid is stronger than phenol, we can look at the stability of the resulting ions after deprotonation:
- When phenol loses a proton, it forms the phenoxide ion (\( C_{6}H_{5}O^{-} \)).
- When carbonic acid loses a proton, it forms the bicarbonate ion (\( HCO_{3}^{-} \)).

### Step 5: Resonance Structures
- The phenoxide ion has several resonance structures, but the negative charge is often on the carbon atom, which is less electronegative than oxygen.
- The bicarbonate ion also has resonance structures, but the negative charge is on the highly electronegative oxygen atoms, making it more stable.

### Step 6: Conclusion
Since carbonic acid is a stronger acid than phenol, it can displace phenol from its sodium salt (sodium phenoxide) in the reaction. Thus, the reaction suggests that:

**Carbonic acid is stronger than phenol.**

### Final Answer
The correct conclusion from the reaction is:
**Carbonic acid is stronger than phenol.**
