Important Questions on Environmental Issues
Given below are two statements:
Statement : In a scrubber, the exhaust from the thermal plant is passed through the electric wires to charge the dust particles.
Statement : Particulate matter (PM ) cannot be removed by a scrubber but can be removed by an electrostatic precipitator.

| Pollutant | Control | ||
| (A) | Particulates | (I) | Catalytic converters |
| (B) | Emissions of automobiles | (II) | Incinerators |
| (C) | Sulphur dioxide | (III) | Electrostatic precipitator |
| (D) | Hospital wastes | (IV) | Cooling towers |
| (V) | Scrubbers |
The correct match is
