C) !a-z? That's the opposite of what we want! We need to match uppercase, not exclude lowercase.

A) :UPPER:? What is this, a special regex command from some obscure programming language? I'll stick with the good old-fashioned [A-Z].

I think :UPPER: is not a common regex command, I prefer using [A-Z] as well.

Hah, E) {AZ}? What is this, a secret code? I think the designers of this exam have been watching too many spy movies.
