X can take 1st/2nd/3rd and 4th position respectively. Other players have the option to come ahead of X but Y should always come behind X.

X in first position with Y anywhere behind X
X - - - - => 4!

X in 2nd pos with any one of the three runners other than Y in 1st pos and the rest behind X
3 X - - - => 3.1.3!

X in 3rd pos with any one of the three runners other than Y in 1st pos and 2nd pos the rest behind X
3 2 X - - => 6.1.2!

X in 4th pos with Y behind X
3 2 1 X 1 => 6

24 + 18 + 12 + 6 = 60

IMO D.
Getting defeated is just a temporary notion, giving it up is what makes it permanent.

Simplest method:

These five people could have been arranged in 5! = 120 ways had there been no condition on them.
The question imposes a condition that X has to be before Y.

Come to think of it, in all the 120 arrangements X will be ahead of Y in 50% of the ways and Y will be ahead of X in 50% ways. There is no bias for any of them, it has to be half-half.

So, X will be ahead of Y in (1/2)*(120) = 60 ways.

[spoiler](D)[/spoiler] is the answer.
