Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → A-III, B-IV, C-I, D-II
(A) Sewage treatment — this matches (III) Flocs. In secondary treatment, useful aerobic microbes grow in the aeration tanks as flocs: masses of bacteria held together with fungal threads in a mesh. They eat up the organic matter and lower the BOD of the effluent.
(B) Ministry of Environment and Forests — this matches (IV) Ganga Action Plan. This Ministry started the Ganga Action Plan and the Yamuna Action Plan to save these rivers from pollution by building sewage treatment plants.
(C) Biological control agent — this matches (I) Trichoderma. Trichoderma species are free-living fungi of the root ecosystem. They control several plant pathogens.
(D) Fermented beverage — this matches (II) Rum. Rum, like whisky and brandy, is made by fermentation with yeast followed by distillation.
