How many times will the following loop run?
i = 0
while i < 10 :
   print(i)
   i = i + 1

Consider the loop and how it changes the counter variable step by step.
Option 0: '0' — If the loop ran 0 times, the print statement would never execute. But the initial i is 0 and the condition i < 10 is true at the start, so the body executes at least once. Therefore this option is incorrect.
Option 1: '9' — This would imply the loop prints 0 through 8 and stops before printing 9, which contradicts the behavior where i starts at 0 and increments by 1 each time until the condition fails. Since i reaches 9 and still satisfies i < 10, the loop will run again to print 9, so this option is incorrect.
Option 2: '10' — This matches the total number of iterations the loop performs. The sequence starts with i = 0 and in each iteration i is increased by 1, continuing while i < 10. The values printed are 0 through 9, which accounts for 10 executions of the loop body. This option aligns with the actual control flow of the loop.
Option 3: '8' — This would indicate only eight iterations occurred, which would require i to reach 8 as the final printed value or the loop to terminate earlier than i reaching 10. However, since i increments by 1 from 0 and the condition is i < 10, the loop does not stop at 8 prints. Therefore this option is incorrect.
In summary, analyzing the loop's initialization (i = 0), the continuation condition (i < 10), and the incremental update (i = i + 1) shows the loop executes exactly 10 times, printing the sequence 0 through 9.
