1. Argon
2. Methane
3. Butane
4. Propane

Answer 1

Correct Answer - Option 1 : Argon

The correct answer is Argon.

• LPG stands for liquefied petroleum gas.
• LPG is composed of hydrocarbons containing three or four carbon atoms. 
• The normal components of LPG thus, are propane (C3H8) and butane (C4H10). 
• LPG is a hydrocarbon-based combustible gas. 
• LPG is the generic name of the butane and propane gases and their mixtures in different proportions. 

• Argon is a chemical element with the symbol Ar and atomic number 18. It is a noble gas. It is in group 18 of the periodic table.  
• Methane gas is found in small quantities in Earth's atmosphere. Methane is the simplest hydrocarbon, consisting of one carbon atom and four hydrogen atoms. 
• Butane is a colorless gas with a faint petroleum-like odor. For transportation, it may be stretched. It is shipped as a liquefied gas under its vapor pressure. 
• Propane is a flammable hydrocarbon gas. It is liquefied through pressurization and commonly used for fuel in heating, cooking, etc.
