D: Cu3(PO4)2

Explanation:

Copper(II) phosphate is a compound that is also known as cupric salt of phosphoric acid. It has the ability to react with string acids and yield their copper salts, like when it reacts with H2SO4, the reaction yields  phosphoric acid and copper salt.

If we talk about the formula, it is because the oxidation no of PO4 is +3 but that for copper is  +2, so when Copper (Cu) and Phosphate (PO4) are combined an exchange of radical occurs which yields the formation of Copper(II) phosphate with the formula  Cu3(PO4)2.
