Answer: B

Explanation:

The while loop starts with i = 0 and checks if the condition i < 5 is true. Since i is initially 0, it enters the loop and prints the value of i. After printing, the statement i += 1 increments i by 1. This process repeats until i reaches 5, at which point the condition i < 5 becomes false, and the loop terminates. Therefore, the loop executes 5 times, printing the values 0, 1, 2, 3, and 4. Option A is incorrect because it would only run once if the condition was set differently, and Option D would only be correct if there was no increment, which would result in an infinite loop.
