Q. Measuring Biological Oxygen Demand (BOD) is a method used for
A) Measuring the activity of Saccharomyces cerevisiae in producing curd on a commercial scale
B) Working out the efficiency of RBCs about their capacity to carry oxygen
C) Estimating the amount of organic matter in sewage water
D) Working out the efficiency of oil driven automobile engines
