Biotic Oxygen Demand
Biological Oxygen Demand
None of the above
Answer is Wrong!
Answer is Right!
The correct answer is C. Biological Oxygen Demand (BOD).
BOD is a measure of the amount of oxygen that is used by microorganisms to break down organic matter in water. It is an important indicator of water quality, as high BOD levels can indicate that the water is polluted.
A. Biological Oxygen Decrease is incorrect because it does not accurately reflect the meaning of BOD. BOD is a measure of the amount of oxygen that is used, not decreased.
B. Biotic Oxygen Demand is incorrect because it is not a common term used to describe BOD. The most common term is Biological Oxygen Demand.
D. None of the above is incorrect because C is the correct answer.
