Match List I with List II
| List I | List II |
|---|---|
| A. Catalytic converter | I. Particulate matter |
| B. Incinerators | II. Organic waste |
| C. Electrostatic precipitator | III. Hospital Waste |
| D. Sewage treatment plant | IV. Carbon monoxide and nitrogen oxides |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → A-IV, B-III, C-I, D-II
(A) Catalytic converter — this matches (IV) Carbon monoxide and nitrogen oxides. Fitted in vehicles, its platinum, palladium and rhodium change CO and nitric oxide into CO2 and nitrogen.
(B) Incinerators — this matches (III) Hospital Waste. Hospital waste carries disease-causing microbes, so it is burnt in incinerators.
(C) Electrostatic precipitator — this matches (I) Particulate matter. It charges dust particles and collects them on plates, removing over 99 per cent of the particulate matter.
(D) Sewage treatment plant — this matches (II) Organic waste. Microbes in the plant break down the organic matter of sewage and lower its BOD.
