Case-Based-II: Natural gas is lighter than air and is a mixture of methane (about 95\%), ethane, propane and butane. Other components found in natural gas include carbon dioxide, helium, hydrogen sulphide and nitrogen. It is highly inflammable and has no odour and cannot be seen. Therefore, before it is sent to the pipelines or storage tanks, it is mixed with a chemical that gives it a strong odour which is almost like that of rotten eggs. This makes it easy to detect in case of any leakage.
The cleanest burning fossil fuel is
a. Kerosene
b. Natural gas
c. \( \mathrm{CO}_{2} \)
d. \( \mathrm{CO} \)
