What Is the Net Ionic Equation for the Complete Neutralization

What is the net ionic equation for the complete neutralization of phosphoric acid with potassium hydroxide?

A) H₃PO₄(aq) + 3OH^-(aq) → 3H₂O(l) + PO₄^3-(aq)
B) H₃P(aq) + 3KOH(aq) → 3H₂O(l) + K₃P(aq)
C) H⁺(aq) + OH^-(aq) → H₂O(l)
D) H₃PO₄(aq) + 3KOH(aq) → 3H₂O(l) + K₃PO₄(aq)
E) 3H⁺(aq) + 3KOH(aq) → 3H₂O(l) + 3K⁺(aq)
