The polyatomic ion among the options given is B. PO43−.

A polyatomic ion is an ion composed of two or more atoms covalently bonded or of a metal complex that can be considered as acting as a single unit in the context of acid/base chemistry or in the formation of salts.

Here's a breakdown of each option:

A. HCl - This is a compound made from a hydrogen atom and a chlorine atom. It's not a polyatomic ion because it only contains one atom of each element.

B. PO43− - This is a polyatomic ion known as phosphate. It contains one phosphorus atom and four oxygen atoms.

C. N2 - This is a diatomic molecule, not an ion. It consists of two nitrogen atoms covalently bonded together.

D. S2− - This is a monatomic ion known as sulfide. It contains only one atom of sulfur.
