D. none of these

Explanation

To solve the question regarding the reaction of nitrobenzene with acetyl chloride in the presence of anhydrous AlCl3, we can follow these steps:

### Step-by-Step Solution

1. **Identify the Reactants**:
- The reactants are nitrobenzene (C6H5NO2) and acetyl chloride (CH3C(=O)Cl).
- Nitrobenzene contains a nitro group (-NO2) attached to a benzene ring.

2. **Understand the Reaction Type**:
- The reaction in question is a Friedel-Crafts acylation, which typically involves the introduction of an acyl group into an aromatic ring.

3. **Consider the Role of AlCl3**:
- Anhydrous AlCl3 acts as a Lewis acid catalyst. It helps to generate an acylium ion (CH3C(=O)+) from acetyl chloride, which is necessary for the Friedel-Crafts acylation mechanism.

4. **Evaluate the Effect of the Nitro Group**:
- The nitro group (-NO2) is a strong electron-withdrawing group. It decreases the electron density of the benzene ring, making it less reactive towards electrophiles.
- In Friedel-Crafts reactions, the presence of strong electron-withdrawing groups (like -NO2) significantly hinders the electrophilic substitution reaction.

5. **Conclusion**:
- Due to the electron-withdrawing nature of the nitro group, nitrobenzene does not undergo Friedel-Crafts acylation with acetyl chloride in the presence of AlCl3.
- Therefore, the reaction does not proceed, and the product formed is none.

### Final Answer:
The reaction of nitrobenzene with acetyl chloride in the presence of anhydrous AlCl3 does not produce any product.
