The correct answer is “A is false but R is true ”.
LPG (Liquefied Petroleum Gas) is not entirely pollution-free. While it is cleaner compared to conventional petrol and diesel, it still produces emissions, albeit lower than those from traditional fuels.

CNG (Compressed Natural Gas) is indeed recommended for use in metropolitan cities in India due to its lower emissions compared to petrol and diesel.
