A. John and Jorge, the messiest eaters at the table, left food all over the place after dinner.
Step-by-step explanation:
An appositive is usually a noun/pronoun that can replace or find out another noun/pronoun in someway or the other. An appositive phase can be of two types -
An appositive phrase=An appositive+Modifiers.
So as to punctuate an appositive - after both the names there should a comma which then separates it from the description of the person (which is the messiest eaters at table) and again a comma which separates the description of the persons from the content.
