Since barium forms a compound with the formula Ba₃(X)₂, it suggests that the polyatomic ion X has a charge of -1 and consists of 13 atoms of B and 1 atom of S. Therefore, the most likely compound formed between sodium and X would be Na₃(X) which simplifies to Na₃X since sodium has a charge of +1. This corresponds to choice D.
