The correct Answer is:
To solve the matching question between Column A and Column B, we will analyze each item in Column A and find its corresponding match in Column B based on their functions and characteristics. ### Step-by-Step Solution: 1. **Identify Column A Items:** - A. Catalytic converter - B. Electrostatic precipitator - C. Earmuffs - D. Landfills 2. **Analyze Each Item in Column A:** - **A. Catalytic converter:** - Function: Catalytic converters are used in automobiles to convert harmful exhaust gases (like unburned hydrocarbons) into less harmful substances (like CO₂ and nitrogen oxides). - Match: This corresponds to (ii) CO₂ and Nitrogen oxide. - **B. Electrostatic precipitator:** - Function: These devices are used in industries to remove particulate matter from waste gases, particularly in power generation. - Match: This corresponds to (i) Particulate matter. - **C. Earmuffs:** - Function: Earmuffs are used to reduce high noise levels by covering the ears. - Match: This corresponds to (iv) High noise level. - **D. Landfills:** - Function: Landfills are used for the disposal of solid wastes. - Match: This corresponds to (iii) Solid wastes. 3. **Final Matching:** - A matches with (ii) CO₂ and Nitrogen oxide. - B matches with (i) Particulate matter. - C matches with (iv) High noise level. - D matches with (iii) Solid wastes. ### Summary of Matches: - A → (ii) - B → (i) - C → (iv) - D → (iii) ### Final Answer: - A: (ii) CO₂ and Nitrogen oxide - B: (i) Particulate matter - C: (iv) High noise level - D: (iii) Solid wastes ---
