As we have learnt, 

Pb^{2+} forms precipitates with the given anions. The color of the precipitates are given below:

Pb^{2+}{+} SO^{2-}_{4}\rightarrow PbSO_{4}\ (white)

Pb^{2+}{+} CrO^{2-}_{4}\rightarrow PbCrO_{4} \ (yellow)

Pb^{2+}{+} 2I^{-}\rightarrow PbI_{2} \ (yellow)

Hence, the correct answer is Option (4)
