Explanation:

- For option 1, 47:2116: If you consider 47 squared, it equals 2209, which is different from 2116.

- In option 2, 53:2703: If you multiply 53 by 51, you get 2703.

- In option 3, 24:528: Multiplying 24 by 22 results in 528.

- For option 4, 68:4488: Multiplying 68 by 66 yields 4488.

From the above calculations, option 1 is inconsistent with the others as it does not seem to follow the operation of multiplying the number with the next even number minus two. Therefore, Option 1 is the odd pair out.
