An aromatic compound (A) on treatment with aqueous ammonia and heating forms compound (B) which on heating with ` Br_2` and ` KOH` froms a compound (C ) of the molecular formula ` C_6 H_7 N`. Write the structures and `IUPAC` names of compounds (A) . (B) and (C ).

Explanation

To solve the problem step by step, we will identify the compounds A, B, and C based on the given reactions and their molecular formulas.

### Step 1: Identify Compound C
We are given that compound C has the molecular formula C₆H₇N. The only amine that fits this formula and is aromatic is aniline, which has the structure:

**Structure of Compound C:**
- Aniline: C₆H₅NH₂
