Explanation:

- The given set is (109, 114, 139). Let's break down the relationships:

- The difference between the first two numbers is 114 - 109 = 5.

- The difference between the second and third numbers is 139 - 114 = 25.

- Here, there's an arithmetic sequence where the difference of consecutive numbers seems like 5 and 25.

- Option 1: (419, 424, 439)

- The difference is: 424 - 419 = 5 and 439 - 424 = 15.

- Differences don’t match the sequence style in the given set.

- Option 2: (268, 302, 237)

- The difference is: 302 - 268 = 34 and 237 - 302 = -65.

- Not related.

- Option 3: (579, 534, 549)

- The difference is: 534 - 579 = -45 and 549 - 534 = 15.

- Not related.

- Option 4: (313, 318, 343)

- The difference is: 318 - 313 = 5 and 343 - 318 = 25.

- This matches perfectly with the pattern in the given set.
