Let's break it down:

- Start with the expression: \(7^2 - 6^2 - 3\).

- Calculate \(7^2\): \(49\).

- Calculate \(6^2\): \(36\).

- Perform the operation: \(49 - 36 = 13\).

- Subtract 3: \(13 - 3 = 10\).

- Add 12: \(10 + 12 = 22\).

Now, let's evaluate the options:

1. Option 1: 12

2. Option 2: 15

3. Option 3: 14

4. Option 4: 22

5. Option 5: 8

- The correct answer is Option 4: 22.
