Are these all thiols?

Hello,
I've recently had a chemistry test, one of the questions asked "which of these are
not
thiols?", and the given answers were:
2,3-dimercaptopropanol
cysteine
coenzyme A
glutathione
I thought they were all thiols?!

Thank you for the reply, that's what I thought too.
The question asked which ones are not a thiol so I was wondering if any of them could be argued to be "not a thiol"...
Maybe it was a trick question. Just feels weird to have a MCQ that requires none of the answers to be checked!
