A. Chemical Oxygen Demand (COD)
B. Biological Oxygen Demand (BOD)
C. Bivariate Oxygen Demand (BOD)
D. Complete Oxygen Demand (COD)
Answer: Option B
Solution(By Examveda Team)
The capacity of the organic and biological matter in a sample of natural water to consume oxygen and the process catalyzed by bacteria is Biological Oxygen Demand (BOD).Biochemical oxygen demand is an analytical parameter representing the amount of dissolved oxygen (DO) consumed by aerobic bacteria growing on the organic material present in a water sample at a specific temperature over a specific period.
The BOD value is most commonly expressed in milligrams of oxygen consumed per liter of sample during 5 days of incubation at 20°C and is often used as a surrogate of the degree of organic water pollution.
