Final Answer:

The statement "This for loop will iterate 5 times: for(i = 12345; i != 0; i /= 10)" is True.

Thus option a is correct.

Step-by-step explanation:

The for loop initializes i to 12345 and continues to iterate as long as i is not equal to 0. In each iteration, i is divided by 10 (i /= 10). Since i starts at 12345 and is divided by 10 in each iteration, the loop will iterate 5 times before i becomes 0. Therefore, the loop will indeed iterate 5 times.

The loop begins with i initialized to 12345. With each iteration, i is divided by 10 (i /= 10). This division operation effectively removes the rightmost digit of i in every iteration. The loop continues until i becomes 0.

Here's a breakdown of the iterations:

1. Iteration 1: i = 12345 / 10 = 1234.5 (in integer division, it's 1234)

2. Iteration 2: i = 1234 / 10 = 123.4 (in integer division, it's 123)

3. Iteration 3: i = 123 / 10 = 12.3 (in integer division, it's 12)

4. Iteration 4: i = 12 / 10 = 1.2 (in integer division, it's 1)

5. Iteration 5: i = 1 / 10 = 0.1 (in integer division, it's 0)

After the fifth iteration, i becomes 0, satisfying the condition for the loop to terminate. Therefore, the loop executes 5 times before i equals 0, confirming that the statement is indeed true.

Therefore option a is correct.
