Hint: The given term is similar to the COD, i.e. chemical oxygen demand in the functionalities. The value of BOD is articulated in milligrams of oxygen. The full form of BOD can be identified.

Complete step by step answer:
-Now, first let us know about the abbreviation BOD. As mentioned, it is similar to the chemical oxygen demand analysis.
-We can say BOD is used to determine the aerobic destructibility of the organic substances, or in other terms it is used to measure the amount of oxygen dissolved in the biological process like metabolic activity of organic molecules.
-Thus, BOD is also used to measure the organic pollution of water bodies. That’s why the treatment of wastewater is considered a priority to reduce its BOD level. It is considered that a BOD value of less than 5 ppm can be regarded as clean water whereas highly polluted water can have a BOD value of 17 ppm or more.
-We can say that BOD has a wide number of applications in the field of chemistry, and biology.
It has main use in the medicinal, and pharmaceutical industry, as it helps to measure the consumption of oxygen.
Thus, we can say that BOD is the measure of oxygen consumption, as its each and every application is related to the field of organic molecules, or organic waste.

So, in the last we can conclude that BOD stands for Biochemical Oxygen Demand.

Hence, the correct option is (A).

We have already discussed about the BOD, i.e. Biochemical Oxygen Demand. One of the major disadvantages of BOD is the amount of time. It takes 5 days to obtain the results. The COD is Chemical Oxygen Demand, it is used to measure the amount of organic molecules in water, but it is less specific; so, it is considered to measure the species that can oxidize chemically and it takes only a few hours to complete and obtain the result.
