A) Use of unleaded petrol.
B) Use of high-sulphur petrol and diesel.
C) Use of catalytic converters in vehicles.
D) Application of stringent pollution-level norms for vehicles.
Correct Answer: B
Solution :
[b] Emissions that are released directly into the atmosphere from the tailpipes of cars and trucks are the primary source of vehicular pollution. But motor vehicles also pollute the air during the processes of manufacturing, refuelling, and from the emissions associated with oil refining and distribution of the fuel they bum. Use of high sulphur petrol and diesel is not taken for reducing vehicular pollution.
