Which option correctly expands the acronym BOD?

Explanation:
BOD measures how much dissolved oxygen microorganisms need to biologically oxidize organic matter in water. Because that oxygen demand comes from biochemical (microbial) processes, the correct expansion is Biochemical Oxygen Demand. The other phrases aren’t standard terms for this acronym, and while some sources use Biological Oxygen Demand, the official and most widely used expansion is Biochemical Oxygen Demand.
