Aniline can be obtained by reduction of nitrobenzene with

Options

A. Fe/HCl
B. Sn/NaOH
C. Electrolytic reduction under strong acidic conditions
D. All of these

Explanation

To solve the question "Aniline can be obtained by reduction of nitrobenzene with," we will analyze the options provided and determine which one is correct.

### Step-by-Step Solution:

1. **Identify the Compound**: We start with nitrobenzene (C6H5NO2), which contains a nitro group (-NO2) attached to a benzene ring.

2. **Understand the Reduction Process**: The reduction of nitrobenzene involves converting the nitro group (-NO2) to an amine group (-NH2), which is the structure of aniline (C6H5NH2).

3. **Evaluate the First Option: Fe and HCl**:
- Iron (Fe) in the presence of hydrochloric acid (HCl) acts as a strong reducing agent.
- This combination can effectively reduce nitrobenzene to aniline.
- The reaction can be summarized as:
\[ \text{C}_6\text{H}_5\text{NO}_2 + 3\text{H}_2 \rightarrow \text{C}_6\text{H}_5\text{NH}_2 + 2\text{H}_2\text{O} \]
- Thus, this option is valid.

4. **Evaluate the Second Option: Sn and NaOH**:
- Tin (Sn) is a reducing agent, but when used in a basic medium (NaOH), it does not effectively reduce nitrobenzene.
- Therefore, this option is incorrect.

5. **Evaluate the Third Option: Electrolytic Reduction under Strong Acidic Conditions**:
- Although electrolytic reduction can reduce nitrobenzene, it typically requires weak acidic conditions, not strong acidic conditions.
- Therefore, this option is also incorrect.

6. **Conclusion**: The only correct method for reducing nitrobenzene to aniline from the given options is using Fe and HCl.

### Final Answer:
Aniline can be obtained by reduction of nitrobenzene with **Fe and HCl**.
