When dilute hydrochloric acid is added to aqueous lead(II) nitrate, a white precipitate of lead(II) chloride is formed. What is the ionic equation for this reaction?

1. APb2+(aq) + 2HCl(aq) → PbCl2(s) + 2H+(aq)
2. BPb2+(aq) + 2HCl(aq) + 2HNO3(aq) → PbCl2(s) + 4H+(aq) + 2NO3−(aq)
3. CPb2+(aq) + 2Cl−(aq) → PbCl2(s)
4. DPb(NO3)2(aq) + 2HCl(aq) → Pb2+(aq) + 2Cl−(aq) + 2HNO3(aq)
