First, we need to write the balanced molecular equation: 
Li2S(aq) + Cu(NO3)2(aq) → CuS(s) + 2LiNO3(aq)

Next, we can break down the soluble ionic compounds into their respective ions: 
2Li+(aq) + S2-(aq) + Cu2+(aq) + 2NO3-(aq) → CuS(s) + 2Li+(aq) + 2NO3-(aq)

Canceling out the spectator ions (Li+ and NO3-), we get the ionic equation: 
S2-(aq) + Cu2+(aq) → CuS(s)

Option D is the correct choice because it represents the balanced molecular and ionic equations for the given reaction.
