Prepare / convert nitrobenzene into aniline.

Explanation

To convert nitrobenzene into aniline, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**: We start with nitrobenzene (C6H5NO2) as our starting material.

2. **Choose a Reduction Method**: The nitro group (-NO2) in nitrobenzene needs to be reduced to an amino group (-NH2) to form aniline (C6H5NH2). We can use either catalytic hydrogenation or a chemical reduction method.
