When аqueоus sоlutiоns of lithium sulfide аnd copper(II) nitrаte are mixed, a reaction may occur.Which of the following is the correct complete ionic equation (if any)?A. 2Li⁺(aq) + S²⁻(aq) + Cu²⁺(aq) + 2NO₃⁻(aq) → CuS(s) + 2Li⁺(aq) + 2NO₃⁻(aq)B. Li₂S(aq) + Cu(NO₃)₂(aq) → CuS(aq) + 2LiNO₃(aq)C. 2Li⁺(aq) + S²⁻(aq) + Cu²⁺(aq) + 2NO₃⁻(aq) → Cu²⁺(aq) + S²⁻(aq) + 2Li⁺(aq) + 2NO₃⁻(aq)D. 2Li⁺(aq) + S²⁻(aq) + Cu²⁺(aq) + 2NO₃⁻(aq) → CuS(s) + Li₂NO₃(s)
