C Correct answer
Explanation

This is the correct answer. The compiler will first reverse the bits of  x and y as we have used ~ (tilde) operator on them. So, the expression becomes: -24 | -43. Now, the compiler will convert -25 and -43 into binary and perform OR operation on them. So, the answer will be -9.
