Are positive integers p and q both greater than n

(1) p-q is greater than n
(2) q>p

Whether following approach is wrong?
1) p-q>n
p>n+q, so p greater than n, but can not be decided whether q > n. Insufficient.
2) q > p, no information about n. so insufficient.

For C
q>p and p>n so, p and q both are greater than n.

If wrong please help.
