Solution

The correct answer is B. 12345

Here's the step by step explanation:

  1. The variable i is initialized to 0.
  2. The for loop checks if i is less than 5. Since i is 0, it is less than 5, so the loop proceeds.
  3. Inside the loop, i is incremented by 1 (i++), making i equal to 1.
  4. The value of i (which is now 1) is printed.
  5. The loop then goes back to the condition check. Now i is 1, which is still less than 5, so the loop proceeds.
  6. Steps 3-5 are repeated until i is no longer less than 5. This happens when i is 5.
  7. So, the loop prints the numbers 1, 2, 3, 4, 5 in order, which corresponds to option B. 12345.
