got the (C) answer with a regular expression of "Ee" (if the [ ] are missing).

got close to (B) by adding up the offsets (but doesn't end right)

answer (A) includes the positions for the [ & ], so I had a go at trying to find these characters: did this with "[\[\]]"

( \: cancels the 'special meaning' of the next character)

Answer: D. Nice one all.  I don't use Match Pattern enough to remember all of the Regular Expression syntax.  Doing this series, and the next, has reminded me of a few things that are really useful.
