    Answer : The correct answer is option A : They are anions.

    Explanation:

    Polyatomic ions are the ions that contain 2 or more different atoms that are covalently bonded to each other.

    Polyatomic ions could be positively charged (Cations) or negatively charged (anions).

    But if we take a look at the most commonly known polyatomic ions, we will see that almost all of them are anions.

    Some examples are given below.

    Nitrate : NO₃⁻

    Sulfate : SO₄²⁻

    Hydroxide : OH⁻

    Phosphate : PO₄³⁻

    Chlorate : ClO₃⁻

    The only positively charged polyatomic ion that is most common is NH₄⁺ ion.

    Hence we can say that, the characteristic that is shared by most simple polyatomic ions is that they are anions.
