D Correct answer
Explanation

The compiler will first convert all of the given values in binary form. So, value of x in binary is 00011000, value of Y in binary is 00101010, value of Z in binary is 00100101 and value of "a" in binary is 00010110. Now, OR operation will be performed on all of them to obtain a single result: (00011000) | (00101010) | (00100101) | (00010110). It will result in 63. So, this is the correct answer.
