The given answer (Option B: 0 1 2 3) is incorrect.
Let’s trace the code:
Initially, i = 0
First iteration: ++i → i becomes 1 → prints 1
Second iteration: ++i → i becomes 2 → prints 2
Third iteration: ++i → i becomes 3 → prints 3
Now i = 3, condition i < 3 is false → loop stops
Final output:
1 2 3
The correct answer is Option A (1 2 3).
