Explanation:

- X sits at one end, with I sitting one seat away from X.

- Nine persons sit between A and I; hence, the arrangement is X, I, 9 in between, and A.

- V is exactly between A and I, so 4 must be between A and V, and 4 between V and I.

- Two persons sit between K and V.

- Four persons separate K and Y, with Y positioned to the right of A.

- More than six persons must sit between I and Y.

- The gap between I and Y is two more than those to the right of V, satisfying the conditions.

If you fit all these conditions together, the total number of people sitting in the row is:

- 18 people fulfill all constraints.

Hence, the correct answer is 18.

Correct answer: Option:4, 18
