Important Points

Hazardous Substance	Major Source
A) Lead	(III) Paint Lead is added to paint to accelerate drying, increase durability, maintain a fresh appearance, and resist moisture that causes corrosion. It is one of the main health and environmental hazards associated with paint.
(B) PCB (Polychlorinated biphenyls)	(I) Electrical Insulation Minimizes or eliminates signal interference between adjacent layers. Maintains adhesion during the assembly temperature cycling. Aids in thermal distribution during assembly. Aids in signal and power integrity
(C) Benzene	(IV) Gasoline Benzene is an essential product used in the production of gasoline. Benzene forms a large part of crude oil, and most of the products manufactured by oil refineries contain benzene in them.
(D) Vinyl Chloride	(II) Plastics Industrial Uses Vinyl chloride is used to make polyvinyl chloride (PVC). PVC is used to make a variety of plastic products, including pipes, wire and cable coatings, and packaging materials.

Hence, the correct answer is (A) - (III), (B) - (I), (C) - (IV), (D) - (II)
