Answer:-

Your correct answer is option 3.

Biochemical Oxygen Demand is connected with Microbes as well as with organic matter also.

Explanation:-

What is Biochemical Oxygen Demand?

It is defined as the required amount of oxygen by the bacteria in order to break down organic matter present in the sample water.

As if large amount of organic matter is given to water then oxygen present in the water will be used up. Which leads to difficulty for the aquatic animals.

In other we can understand that B.O.D. is a type of data which is required for measuring the amount of organic material in water in terms that how much amount of oxygen will be needed biologically in the process.

B.O.D. of clean water would be not more than 5ppm and on the other side 17ppm or more is the B.O.D. for polluted water.
