Write a Balanced Half Equation for the Following Couple

Multiple Choice

Write a balanced half equation for the following couple:
NH₄⁺(aq) (acidic)

A) NO₃^-(aq) + 3 H₂O(l) → NH₄⁺(aq) + 10 H⁺(aq) + 8 e^-
B) NO₃^-(aq) + 4 H⁺(aq) + 3 e^- → NH₄⁺(aq) + 3 H₂O(l)
C) NO₃^-(aq) + 4 H⁺(aq) → NH₄⁺(aq) + 3 H₂O(l) + e^-
D) NO₃^-(aq) + 8 H⁺(aq) + 8 e^- → NH₄⁺(aq) + 3 H₂O(l)
E) NO₃^-(aq) + 10 H⁺(aq) + 8 e^- → NH₄⁺(aq) + 3 H₂O(l)
