Explanation:

Let's analyze the pattern:

- The relationship between 12 and 145 might involve some mathematical operation.

- Similarly, we need to find the number related to 8 using a similar pattern.

Steps to find the pattern:

- Look for operations like addition, multiplication, or exponentiation:

- 12 multiplied by 12, plus 1, equals 145: (12 \* 12) + 1 = 145

- Apply the same pattern to 8:

- 8 multiplied by 8, plus 1, equals 65: (8 \* 8) + 1 = 65

Now let's evaluate the options:

1. 60: Too low to match the pattern.

2. 85: Does not match the pattern.

3. 65: Matches the pattern of the operation.

4. 73: Does not match the pattern.

The correct option is Option 3: 65.
