    Answer : Option B

    Explanation :

    The macro MAX(a, b) (a > b ? a : b) returns the biggest value of the given two numbers.

    Step 1 : int x; The variable x is declared as an integer type.

    Step 2 : x = MAX(3+2, 2+7); becomes,

    => x = (3+2 > 2+7 ? 3+2 : 2+7)

    => x = (5 > 9 ? 5 : 9)

    => x = 9

    Step 3 : printf("%d\n", x); It prints the value of variable x.

    Hence the output of the program is 9.
