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.

Definitely, it would be more useful to return an error code or something.

I think the correct statements are B) the second open () argument is optional and C) instd, outstd, errstd are the names of pre-opened streams.

I'm pretty sure B is also true. The second argument to open() is the file mode, which can be specified optionally.

Yes, you're right. B is also true. The second argument is optional for open().

You're right, I misunderstood. A and C make more sense now.

But the second argument in open() is not optional, it is mandatory.

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