This question was previously asked in

RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)

Liquid Petroleum Gas

Liquefied Petroleum Gas

Liquid Petrol Gas

Liquided Petrol Gas

The correct answer is

Liquefied Petroleum Gas

LPG Full Form: Liquefied Petroleum Gas

The question asks for the correct full form of the abbreviation LPG.

Option B: Liquefied Petroleum Gas is the correct full form of LPG.

Reasoning:

LPG is a common fuel. The term refers to a mixture of hydrocarbon gases, primarily propane and butane, that are liquified under pressure for storage and transport.

The 'L' in LPG specifically stands for Liquefied, indicating the state of the gas under pressure.
The 'P' stands for Petroleum, derived from crude oil refining processes.
The 'G' stands for Gas.

Therefore, the correct expansion is Liquefied Petroleum Gas.

Incorrect Options Analysis:

Option 1 (Liquid Petroleum Gas): Incorrect because 'Liquid' is not the precise term; 'Liquefied' describes the state change due to pressure.
Option 3 (Liquid Petrol Gas): Incorrect because 'Petrol' is not the standard term used in the abbreviation LPG; 'Petroleum' is correct. Also, 'Liquid' is imprecise.
Option 4 (Liquided Petrol Gas): Incorrect because 'Liquided' is not a standard English word in this context, and 'Petrol' is incorrect.
