Answer 1

Answer: (D)

PCB

Burning plastics can release polychlorinated biphenyls (PCBs) and dioxins. Dioxins are produced during the manufacture of materials containing chlorine, including PVC and other chlorinated plastic feedstocks.

Polychlorinated biphenyl (PCB) belong to a broad family of man-made organic chemicals, known as chlorinated hydrocarbons. PCBs cause cancer, as well as a variety of other adverse health effects on the immune system, reproductive system, nervous system, and endocrine system.
