Answer:

The answer to your question is: the third option

Step-by-step explanation:

SO₄ ⁻²

Polyatomic ion is a molecule composed by 2 or more atoms, so SO₄⁻² is a polyatomic ion.

Cation: is an ion that has a positive charge.

Anion: is an ion that has a negative charge.

so SO₄ ⁻² is a polyatomic anion because it is composed by two elements and has a negative charge.

It is a polyatomic anion because it has more than one atom and a negative charge.
