Solution:
k - m - p = k - (m+p).
First consider (1) alone.
m is even and p is odd.
So m+p is odd.
k is even.
So k - (m+p) is odd.
Or (1) alone is sufficient to answer the question.
Next consider (2) alone.
Since k, m and p are consecutive integers, let m = k+1 and p = k+2.
So m+p is 2k+3.
Or k - (m+p) is k - (2k+3) = -k - 3.
So the value of k - (m+p) depends on whether k is even or odd.
Or (2) alone is not sufficient.
The correct answer is hence (A).
