Which of the following has the highest calorific value (kcal/Nm3) ?
Correct answer: D. LPG
- A. Carburetted water gas
- B. Gobar gas
- C. Natural gas

Explanation
LPG is rich in propane and butane, whose higher hydrocarbons release much more heat per normal cubic metre than methane-rich natural gas or low-calorific producer-type gases. Thus LPG has the highest volumetric calorific value here.
