Draw the structure, give IUPAC names and indicate primary,secondary and tertiary amines in the following:
Five isomeric amines of formula `C_7 H_9 N` having one benzene ring

Explanation

To solve the problem of drawing the structures, giving IUPAC names, and indicating primary, secondary, and tertiary amines for the five isomeric amines with the formula C7H9N containing one benzene ring, we can follow these steps:

### Step 1: Identify the Isomers
We need to draw five isomeric structures for amines with the formula C7H9N that each contain a benzene ring. The isomers will differ in the position of the amine group (NH2) and the methyl (CH3) group.

### Step 2: Draw the Structures
1. **Isomer A**:
- Structure:
