Explanation:

Let's break down the logic step by step:

- The pair is 11 : 123.

- Look for a pattern: 11 × 11 = 121, and 121 + 2 = 123.

- The pattern is: n : n × n + 2.

Now, applying the same logic to 12:

- 12 × 12 = 144

- 144 + 2 = 146

Let's check the options:

- Option 1: 144 (This is just 12 × 12)

- Option 2: 146 (This follows the pattern above)

- Option 3: 148 (Doesn’t fit)

- Option 4: 150 (Doesn’t fit)

So, the correct answer is Option 2: 146.
