Measuring Biochemical Oxygen Demand (BOD) is a method used for:

  1. A
    Working out the efficiency of R.B.Cs. about their capacity to carry oxygen
  2. B
    Estimating the amount of organic matter in sewage water
  3. C
    Working out the efficiency of oil driven automobile engines
  4. D
    Measuring the activity of Saccharomyces cerevisiae in producing curd

Solution & Step-by-step Explanation

BOD is the amount of oxygen required by bacteria and other microorganisms to decompose the organic matter in a given volume of water at a certain temperature. It is a direct measure of the organic pollution level in water (e.g., sewage). High BOD indicates high organic waste content.
