public class Test {
    public static void main(String[] args) {
        int a = 3;
        int b = 5;
        int c = a * b + 2;
        System.out.println(c);
    }
}

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

The expression `a * b + 2` follows Java operator precedence: multiplication has higher precedence than addition, so it evaluates as `(a * b) + 2`. Given `a = 3` and `b = 5`, `3 * 5 = 15`, then `15 + 2 = 17`. Therefore, option C is correct. Option A is wrong because the code compiles successfully (no error). Option B (25) would result from `(a + b) * 2` or similar misinterpretation. Option D (21) would result from `a * (b + 2)`. Only option C matches the correct calculation.
