High value of BOD (Biochemical Oxygen Demand) indicates that: [2015 RS...
(a) BOD (Biochemical Oxygen Demand) is a method which measures the level of water pollution. The polluted water has bacteria and many other microorganisms which consume the dissolved oxygen of water. The higher the BOD, the lower would be the dissolved oxygen in polluted water. The high value of BOD indicates the highly polluted water

High value of BOD (Biochemical Oxygen Demand) indicates that: [2015 RS...
Explanation:
BOD (Biochemical Oxygen Demand) is the amount of oxygen required by microbes to decompose organic matter present in water. The higher the value of BOD, the higher the amount of organic matter present in water.
Water pollution is caused by the discharge of industrial effluents, sewage, and other organic matter into water bodies. These organic matters are decomposed by microbes present in the water. During decomposition, microbes consume oxygen to break down the organic matter.
When the amount of organic matter in water is high, the microbes require more oxygen to decompose the organic matter. As a result, the BOD value increases. A high value of BOD indicates that the water is highly polluted with organic matter.
Therefore, option 'C' - water is highly polluted - is the correct answer.
