A)	BOD	I)	Treatment of sewage
B)	KVIC	II)	Measure of organic matter in water
C)	LAB	III)	Biological methods for controlling plant diseases
D)	STPS	IV)	Increases vitamin $B_{12}$
		V)	Production of biogas

• A. A- IV, B- III, C- II, D- V
• B. A- V, B- II, C- III, D- I
• C. A- II, B- I, C- IV, D- V
• D. A- II, B- V, C- IV, D- I

Answer 1

The correct option is D A- II, B- V, C- IV, D- I

BOD is biochemical oxygen demand which refers to the amount of oxygen that would be consumed if all the organics in one liter of water were oxidized by the bacteria. So, A matches with II
KVIC is the model of floating drum model of biogas which uses a metal gas holder that floats in the slurry. So, B matches with V.
STPs are sewage treatment plants. So, D matches with I.
Thus, the correct answer is (D)
