A, C, and D all sound plausible to me. I'm going to go with those three just to be safe.

Haha, open() returning None? That's the equivalent of your car's owner's manual being blank. Not very useful!

D definitely can't be right. What kind of programmer would return None for a failed file open? That's just silly.

User1: I agree, returning None for a failed file open doesn't make sense.

A and C seem correct to me. The open() function returns a file descriptor, not None.
