D is definitely right, but I'm not sure about B. Wait, is this a trick question? *sweats nervously*

Well, at least they didn't ask about the 'a' mode. That one always trips me up!

I thought the open() function had more than two arguments? This question seems a bit too simple.

B and D are correct. Closing a file is done with the close() function, not closefile().

I'm not sure about C, though. It seems like if the file doesn't exist, open ( ) with 'r' mode should still work.

I agree with you, Tricia. A and D make sense because closefile ( ) function is used to close an open file and when opening a file with 'w' mode, the previous content is lost.
