I’m pretty sure ? is not for one or more times, but I can’t recall if it’s zero or one. I should have reviewed more before the exam!

I feel like I might confuse ? with * sometimes, but I think it’s about matching zero or one occurrences.

I remember practicing a question about quantifiers, and I think ? is related to matching zero or one times.

I'm not totally confident, but I think the ? symbol matches the preceding qualifier one or more times. That sounds right, so I'll go with option A.

Ah, I remember learning this in class. The ? symbol means the preceding qualifier can match zero or more times. So the correct answer is B.

Hmm, I'm a bit confused on this one. I know the ? symbol is used for quantifiers, but I can't remember if it's for zero or one, or one or more. I'll have to think this through carefully.

Wait, is the ? symbol a wildcard that matches anything? I'm just kidding, I know it's for matching the preceding qualifier zero or one times. Easy peasy!

Option C is the way to go here. The ? symbol is a greedy quantifier, and that's exactly what the question is asking for.
