Step 1
: Recall the definition of a conjugate acid.

A conjugate acid is formed when a base accepts a proton (H+). In this case, we are looking for the conjugate acid of H^2PO^4 -, which is a base.

Step 2
: Identify the base losing a proton to form H^2PO^4 -.

The base that loses a proton to form H^2PO^4 - is H^3PO^4. This is because H^2PO^4 - is the conjugate base of H^3PO^4.

Final Answer

The conjugate acid of H^2PO^4 - is H^3PO^4 (option D).
