Correct Answer - Option 4 : 17

Here we have to find the minimum no. of persons in the row, hence we will consider the case of overlapping.

Total number of persons = (Sum of positions of both persons) – (Number of persons in between them) – 2

→ (11 + 12) – 4 – 2

→ 23 – 4 – 2

→ 19 – 2

→ 17

Hence, minimum number of the persons in the row is 17.
