Solution
The correct option is D COD and BOD
COD or Chemical Oxygen Demand is the total measurement of all chemicals in the water that can be oxidized. BOD- Biochemical Oxygen Demand is supposed to measure the amount of food (or organic carbons) that bacteria can oxidize.These are a major pollution indicator. Brewery and sugar factory wastes alter the quality of water body by increasing COD and BOD. Higher values of these parameters indicate the contamination of water due to the accumulation of salts, minerals from the industrial wastewater to the soil and leaching to the groundwater and harmful for domestic purpose.
