Which of the following enhances B.O.D. of water ?

Solution
The correct option is B Sugar mill effluents
B.O.D. or Biochemical oxygen demand is the amount of dissolved oxygen which is required by the aerobic organisms during the decomposition of organic matter. It is measured at a specific temperature and specific period of time. The wastes from the sugar mill effluents are directly poured into the water bodies which enhances the demand of required oxygen to completely oxidize the organic compounds to carbon dioxide which leads to overall increase in biochemical oxygen demand.Thus, the correct answer is option A.
