19 : 40

21 : 45

9 : 20

14 : 30

- Let's examine the relationships between the numbers in each pair.

- Option 1: 19 and 40 can be related as 19 * 2 + 2 = 40.

- Option 2: 21 and 45 can be related as 21 * 2 + 3 = 45.

- Option 3: 9 and 20 can be related as 9 * 2 + 2 = 20.

- Option 4: 14 and 30 can be related as 14 * 2 + 2 = 30.

- Three pairs (19:40, 9:20, and 14:30) have a pattern: multiply by 2, then add 2.

- Option 2 doesn't follow this pattern, as it uses (multiply by 2, then add 3).

- ? Option 2 (21:45) is the odd one out.
