I think the answer is A) It prints: el because the while loop will iterate through each character in the string 'Hello'.

D) It prints: o. Wait, what? Why would it print just the last character? I must be missing something here.

C) It prints: H. I think this is a trick question, and the code actually only prints the first character of the string.
