hpo₄
h₃po₃
i dont know yet

Explanation:

Step1: Recall phosphate ion formula

The phosphate ion is $\text{PO}_{4}^{3 - }$.

Step2: Add hydrogen ions to form acid

To form an acid, we add hydrogen ions ($\text{H}^+$). Since the charge of phosphate ion is - 3, we need 3 $\text{H}^+$ ions. The acid formed is $\text{H}_{3}\text{PO}_{4}$.

Answer:

B. $\text{H}_{3}\text{PO}_{4}$
