Answer

To calculate the value of y:

Calculate ceil(25.0/6): This evaluates to 5 (because 25.0/6 is approximately 4.1667, so the ceiling is 5).
Calculate 30 mod 6: This evaluates to 0 (since 30 is divisible by 6).
Calculate round(15.0/4): This evaluates to 4 (because 15.0/4 is 3.75, which rounds to 4).

Thus, y is calculated as:

5 + 0 - 4 = 1

So the final answer is C. 1.
