Solution

The correct option is A Biochemical oxygen demand
Biochemical oxygen demand is the amount of dissolved oxygen required by aerobic organisms to break down organic matter in a given water sample of unit volume at a certain temperature over a specific time period. It gives a measure of the effectiveness of a wastewater plant and also use of water from a drinking water body. Thus the correct answer is option A
