Question

What is the full form of LPG?
(a) Liquid plain gas
(b) Liquified petroleum gas
(c) Light petrol gas
(d) Liquified plain gas

Answer 1

Hint: The red gas cylinders in your kitchen are filled with LPG, moreover, the refrigerator you use has LPG filled inside it! And from the options as well, it is evident that LPG is a gas.

Complete answer:
If we happen to trace the brief history of LPG, we know that LPG is prepared by refining petroleum or "wet" natural gas, and is almost entirely derived from fossil fuel sources, being manufactured during the refining of petroleum (crude oil) , or extracted from petroleum or natural gas streams as they emerge from the ground.
We see that this background check has helped us in concluding that LPG is a constituent product if petroleum, and hence, the alternatives which do not contain ‘petroleum’ are incorrect.
Option (a) is incorrect because the expansion of LPG should not contain ‘Plain’.
Option (b), as we know, is the correct answer as it is the right elaboration of the acronym given to us in the question.
Option (c) is incorrect because, since we know that the gas is ‘wet’ in nature, it has to be in liquid form and hence the expansion of ‘L’ is wrong, making the alternative wrong.
Lastly, as we know already, option (d) is not correct because again, the middle word should be petroleum and not plain, as LPG is made up of petroleum.

Note: We should not get confused between LPG and Natural Gas, they are both two totally different products, although with some very similar uses.
