But the question specifies that it should be at the beginning of a line, so I still think A) is correct

I'm no regex expert, but B seems the most straightforward to me. Why make it more complicated than it needs to be?

D is hilarious, but I don't think 'B[A-Z]{4},\b\g' is a valid regex. Gotta love the creativity, though!

I'm going with A. \b\w{4},\b ensures we're matching a whole word, not just four random capital letters.

C is the way to go. /^\w{4},\b/ will match the exact pattern we're looking for.

Great, thanks for confirming. C /^\w{4}\b/ is the search operator that the analyst should use to find the specific text string at the beginning of a line with four capital alphabetic characters.
