The correct options are
A BOD will be more for that sample in which a higher amount of organic waste is present
C A sample with lower BOD is more suitable for aquatic life
D BOD will be higher for that sample of water which has more number of microorganisms present in the sample
  • Biochemical oxygen demand increases as the organic waste increases, which is consumed by microorganisms.
  • If BOD is higher it means that the dissolved oxygen is less for aquatic life.
