Explanation:

- The given pairs seem to relate two numbers based on a hidden pattern.

- In Option 1: 78 : 127, both numbers are prime numbers spread out larger over 49.

- In Option 2: 61 : 97, both numbers are prime numbers spread out at a difference of 36.

- In Option 3: 56 : 136, 56 is not a prime number, but 136 is not a prime number either.

- In Option 4: 25 : 89, 25 isn't a prime number, but 89 is a prime.

The pattern for most pairs seems to involve one prime and one non-prime or numbers spread distinctively. Option 3 is odd as neither is prime or follows the transformation logic.

Option 3: 56 : 136 is correct.
