E.

From 1: if P is 0 and Q is 1 then, K will be an integer. But, if P is 1 and Q is 2, then K will not be an integer.

From 2: N cannot be 0. For positive N, K is an integer. But, for negative N, K is not an integer (except for -1).

Combining 1 and 2,
P/(P+1) = N^N....here right side cannot be zero and any other value will not satisfy both sides.
