Correct Answer: A

Explanation


public class LoopTest {
    public static void main(String[] args) {
        int count = 0; // to count iterations
        
        for (int i = 11; i <= 30; i += 2) {
            System.out.println("i = " + i);
            count++;
        }
        
        System.out.println("Total iterations: " + count);
    }
}

Option (a)

for (int i = 11; i <= 30; i += 2)

Sequence: 11, 13, 15, …, 29
Total iterations: (30-11)/2 + 1 = 10 ✅
Looks correct.

Option (b)

for (int i = 11; i <= 30; i += 3)

Sequence: 11, 14, 17, …
Iterations: (30-11)/3 + 1 = 7 ❌
Not correct.

Option (c)

for (int i = 11; i < 20; i++)

Sequence: 11, 12, …, 19
Iterations: 20-11 = 9 ❌
Not correct.

Option (d)

for (int i = 11; i <= 21; i++)

Sequence: 11, 12, …, 21
Iterations: 21-11+1 = 11 ❌
Not correct.

✅ Answer: (a) for (int i=11;i<=30;i+=2)
