Aqueous solutions of lithium sulfide and copper (II) nitrate are mixed. Give the complete ionic equation for this reaction (if any).

• A. 2Li⁺(aq) + S^2-(aq) + Cu²⁺(aq) + 2NO₃^-(aq) → CuS(s) + 2Li ⁺(aq) + 2NO₃^-(aq)
• B. Li⁺(aq) + SO₄^2-(aq) + Cu +(aq) + NO₃^- (aq) → CuS(s) + Li+(aq) + NO₃^-(aq)
• C. 2Li⁺(aq) + S^2-(aq) + Cu²⁺(aq) + 2NO₃^- (aq) → Cu²⁺(aq) + S^2-(aq) + 2LiNO₃(s)
• D. Li⁺(aq) + S^-(aq) + Cu⁺(aq) + NO₃^-(aq) → CuS(s) + LiNO₃(aq)
• E. NO REACTION
