In this question, we have a reaction between two ionic compounds, Potassium chloride, KCl, and Lead (II) nitrate, Pb(NO3)2, and the complete and balanced reaction between these two compounds is the following:
Pb(NO3)2 (aq) + 2 KCl (aq) ---> PbCl2 (s) + 2 KNO3 (aq)
According to this balanced reaction, we can see that the only possible option for this question will be the solid PbCl2
Therefore the answer will be the 2nd option
