​Which of the following is the full form of PCB?​

Correct option is C

The full form of PCB is Polychlorinated Biphenyls. PCBs are a group of man-made organic chemicals consisting of carbon, hydrogen, and chlorine atoms. They were widely used in electrical equipment like transformers and capacitors because of their chemical stability and insulating properties. However, due to their toxicity and persistence in the environment, their production was banned in many countries.

Information Booster:
PCBs are composed of biphenyl molecules with varying numbers of chlorine atoms attached.

They are environmentally persistent and bioaccumulative, causing harmful effects on wildlife and humans.

Exposure to PCBs is linked to cancer, immune system suppression, and neurological damage.

PCBs were used in various industrial applications, including coolants, lubricants, and plasticizers.

Due to their stability, PCBs do not easily break down in the environment, leading to long-term contamination.

Global agreements such as the Stockholm Convention regulate and aim to eliminate PCBs.

Additional Information:​
Poly Cyclic Benzene refers to aromatic hydrocarbons with multiple benzene rings fused together, common in fossil fuels but unrelated to PCBs.

Poly Chlorinated Benzene refers to chlorinated benzene compounds but is not the correct term for PCBs.

Poly Cyclic Bi phenyls is a misnomer; the correct term involves biphenyl structures, not polycyclic.
