Solution
The correct option is C BOD
(a) PSC (polar stratospheric clouds) are a special type of clouds formed over Antarctica in winter that play important role in ozone layer depletion.
(b) PCB (polychlorinated biphenyls) are toxic chemicals with high stability and resistance to oxidation. These are used for fluids in transformers and capacitors.
(c) BOD (biochemical oxygen demand) is a measure of dissolved oxygen that would be needed by the microorganisms to oxidise organic and inorganic compounds present in polluted water.
(d) COD(chemical oxygen demand) is the amount of oxygen, in ppm, that would be required to oxidise the contaminants.
