Vedclass · Answer

(A) $BOD$ (Biochemical Oxygen Demand) refers to the amount of oxygen that would be consumed if all the organic matter in one liter of water were oxidized by bacteria.Therefore,$A$ is correct because $BOD$ measures the organic matter content in water.$R$ is also correct because a higher $BOD$ indicates more organic matter,which means higher pollution,while a lower $BOD$ indicates less organic matter,meaning lower pollution potential.Thus,both $A$ and $R$ are correct.

$A$ - $BOD$ is a measure of the organic matter present in the water.
$R$ - The lower the $BOD$ of water,the lower is its polluting potential.
