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.Greater $BOD$ indicates higher pollution levels due to organic matter.When organic matter increases, microorganisms consume more oxygen for decomposition, leading to a decrease in dissolved oxygen.Therefore, the statement "The amount of dissolved oxygen in water increases, the $BOD$ increases" is incorrect because an increase in $BOD$ actually leads to a decrease in dissolved oxygen.
