Reason (R): Plying of CNG fuelled buses is recommended for metropolitan cities of India.

Select the correct answer using the code given below:
Code:

  1. Both A and R are true and R is the correct explanation of A
  2. Both A and R are true but R is not the correct explanation of A
  3. A is true but R is false
  4. A is false but R is true

Answer:

Option D: A is false but R is true

Detailed Solution:

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.
