I'm having a slash of a time trying to decide, but I'm leaning towards option C. Gotta love those grep commands!

This question is a real slash-and-burn, isn't it? I'm glad I read the options carefully.

I was about to choose option A, but then I realized that it would print the lines that *do* end with a slash, not the ones that don't. Good catch, Bette!

Yes, you're right. Option A would print lines that end with a slash, not the ones that don't.

I agree with Mona, because the -v option in grep is used to invert the match

Hmm, I think option C is the correct answer. The -v flag in grep is used to invert the match, so it will print the lines that don't end with a slash.
