Option A looks good to me. It matches alphanumeric strings between 5 and 30 characters, which is exactly what the analyst needs.

That makes sense, we need to consider both letters and numbers in the string.

I disagree, I believe the correct answer is C) /^[a-zA-Z]{5,30}$/ because we are looking for alphanumeric characters only.

But wouldn't we want to include numbers as well in the alphanumeric string?
