I recall a similar question where we had to identify valid formats. I think B and C could be the right answers, but I'm not completely confident.

I'm feeling pretty confident about this one. The pattern is straightforward, and I can see that options A and E match it.

Okay, I think I've got this. The pattern is looking for a sequence of digits with 'd' characters in between. Let me double-check the options.

I'm just glad they didn't ask us to code the regular expression. That would have been like trying to juggle chainsaws while riding a unicycle.

E) 209165200224 is the obvious choice. It's like they're asking us to find the needle in a haystack, but the needle is on fire and the haystack is made of glue.

I'm not sure about this one. The question didn't specify the pattern, so it's hard to know for sure. Maybe A) or D) could work too?

But what about A)? It also has numbers followed by 'd' and then another number. It could be a match too.
