Explanation:

- The given pair is 20 : 68.

- To find the relationship, notice that 20 * 3 + 8 = 68.

- We'll check each option to find a similar pattern.

Option 1: 5 : 18

- Calculation: 5 * 3 + 3 = 18

- Doesn't match, as the addend isn't 8.

Option 2: 30 : 110

- Calculation: 30 * 3 + 20 = 110

- Doesn't match, as the addend isn't 8.

Option 3: 25 : 90

- Calculation: 25 * 3 + 15 = 90

- Doesn't match, as the addend isn't 8.

Option 4: 12 : 30

- Calculation: 12 * 3 + 6 = 30

- Doesn't match, as the addend isn't 8.

- None of the options match the exact pattern given in the original pair.
