(D) $BOD$ stands for Biochemical Oxygen Demand. It is a measure of the amount of dissolved oxygen required by aerobic microorganisms to decompose the organic matter present in a given volume of water. When water is highly polluted with organic waste,microorganisms consume more oxygen to break down this waste. Therefore,a high $BOD$ value indicates that the water contains a large amount of organic pollutants,signifying very high water pollution.
