A. Manganese (II) Phosphate Mn3 (PO4) 2

Explanation: The cation combines with anion through coloumbic forces to form an ionic compound.

The cation combines with anion in the ratio of 3:2 so as to form a neutral and stable compound named as Manganese (II) phosphate.

The IUPAC name of ionic compounds are written as:

First the name of the cation is written with its oxidation state in brackets. Then the name of the anion is written.
