D. phenol

Answer

To solve the question regarding the reaction of benzaldehyde with acetic anhydride in the presence of sodium acetate, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants:**
The reactants in the given reaction are:
- Benzaldehyde (C₆H₅CHO)
- Acetic Anhydride ((CH₃CO)₂O)
- Sodium Acetate (CH₃COONa)

2. **Understand the Reaction Type:**
This reaction is known as the Perkin Reaction, which typically involves the condensation of an aromatic aldehyde with an anhydride in the presence of a base (in this case, sodium acetate).

3. **Write the Reaction:**
The reaction can be represented as:
\[ C_6H_5CHO + (CH_3CO)_2O \xrightarrow{CH_3COONa} \text{Product} \]

4. **Determine the Product:**
The product formed from this reaction is Cinnamic Acid (C₆H₅CH=CHCOOH).

5. **Final Equation:**
The complete reaction can be summarized as:
\[ C_6H_5CHO + (CH_3CO)_2O \xrightarrow{CH_3COONa} C_6H_5CH=CHCOOH \]

### Conclusion:
The product of the reaction is **Cinnamic Acid**.
