Solution:

In this problem, two persons Mr. X and Mr. Y have to be seated in a railway compartment that has six vacant seats.

To find the number of ways in which they can occupy the seats, we need to use the permutation formula.

Total number of ways to choose 2 persons out of 2 is = 2C2 = 1
Number of ways in which the two persons can occupy the six seats = 6P2 = 6!/(6-2)! = 6 × 5 = 30

Therefore, the correct answer is option D, i.e., 30.
