Vedclass · Answer

(C) The $BOD$ (Biochemical Oxygen Demand) value is a measure of the amount of dissolved oxygen required by bacteria to decompose organic matter present in a water sample.Clean water typically has a $BOD$ value of less than $5 \, ppm$.Highly polluted water,which contains a significant amount of organic waste,typically has a $BOD$ value greater than $17 \, ppm$.Comparing the given values:$A = 3 \, ppm$ (Clean)$B = 18 \, ppm$ (Highly polluted)$C = 21 \, ppm$ (Highly polluted)$D = 4 \, ppm$ (Clean)Therefore,samples $B$ and $C$ are highly polluted.

The measured $BOD$ values for four different water samples $(A - D)$ are as follows:
$A = 3 \, ppm; B = 18 \, ppm; C = 21 \, ppm; D = 4 \, ppm.$
The water samples which can be called as highly polluted with organic wastes,are .... .
