B?

1) is not sufficient

2)
x > 5y
and n > x => n > 5y
Take the Limiting case (x/y) ^ n > (5y/y)^5y > 5^5y
For any value of y (positive integer) 5^5y > 1000

I think it's B.
From 1: n>y, (x/y)^n may or may not be greater than 1000
Example x=y=1 and n=2 and 1<1000. But if x=2, y=1, n=11, then 2^11>1000. Thus, insuff.

From 2: since x, y, n are positive integers, they must be at least 1.
x>5y, n>5y, and n>x. Even if the smallest value of x,y,z are picked, which is y =1, x=6 and n=7 and 6^7>1000. Suff

Ans B
