dental anatomy question

I got a question on a dental anatomy test that asks which of the following has central pit?
with four answer choices as all the premolars.
Obviously the best choice is mandibular second premolar (because of 3 cusp type) which was choice D. But before the test I could've sworn that I read somewhere or saw some kind of picture of maxillary 1st having a central pit. So I jumped on the choice A (the first one) which was the 1st maxillary premolar. Is there "never" a central pit in maxillary 1st premolar ever? Shouldn't the test have said which of the following is most likely to have a central pit (which is a board question I saw somewhere and I know the right answer is mandibular 2nd premolar)?
P.S. If you know any text, article, or picture that supports it, if you would let me know that would be even nicer!

maxillary first and second premolars normally have a mesial and distal pits, I think. Mandibular second premolars with the Y cusp type have a central pit. and of course mandibular first premolars have the mesial and distal fossa snake eye pits.

I'm pretty sure there is no central pits on a max first molar. Oh and BTW don't try to think too much about a Dr. J question. You'll just end up going crazy, because most of the time they don't make any sense
