    Explanation:

    Certainly! Let's examine the number pairs:

    - 5 : 7

    - Both numbers are consecutive prime numbers.

    - 31 : 41

    - Both numbers are prime.

    - The difference between them is 10.

    - 13 : 19

    - Both numbers are prime.

    - The difference between them is 6.

    - 17 : 23

    - Both numbers are prime.

    - The difference between them is 6.

    Correct Answer: 5 : 7

    Explanation:

    - In options 2, 3, and 4, the differences between the prime numbers (10 for option 2, and 6 for options 3 and 4) show a pattern.

    - Option 1, with a difference of 2, stands out as every other set has a larger gap, making it the odd one out.
