Here's why:

* Cr represents the Chromium element.

* PO4 represents the phosphate ion (PO₄³⁻).

* Since the phosphate ion has a -3 charge, and Chromium can have multiple oxidation states, we need to indicate the charge of Chromium in the compound. In this case, Chromium has a +3 charge (Cr³⁺) to balance the -3 charge of the phosphate ion.

Therefore, the correct name is Chromium(III) Phosphate.
