Sentence Correction (SC) | Re: While most of the earliest known ball courts in Mesoamerica date to 90

Hi GMATNinja, Experts,

I believe that options B and D can also be discarded as they change the meaning.

They imply that a single painting was found. Moreover, it is unclear if the painting was "on ceramics" or the painting was of "representation of ballplayers on ceramics".

Please confirm if this understanding is correct
