LPG stands for Liquefied Petroleum Gas.


It is a mixture of light hydrocarbon gases, mainly Propane (\(C_3H_8\)) and Butane (\(C_4H_{10}\)).


While it contains both, Butane is generally considered the major constituent, especially in the context of domestic cooking gas cylinders in warmer regions.


Methane (\(CH_4\)) is the primary component of Natural Gas and Compressed Natural Gas (CNG), so option (A) is incorrect.


Ethane and Propane are present but are not the primary answer when Butane is listed as a distinct option in this context.


Therefore, option (B) is the correct answer.

Ultraviolet (UV) radiation is a type of electromagnetic radiation that comes from the sun and artificial sources.


When the skin is exposed to excessive UV radiation, it penetrates the skin layers and damages the DNA within skin cells.

Rocket engines require high-efficiency propellants to generate the immense thrust needed to reach space.


Liquid Hydrogen (\(LH_2\)) is a lightweight and extremely powerful fuel used in cryogenic rocket engines.


When burned with an oxidizer like Liquid Oxygen (\(LOX\)), it produces a very high specific impulse (efficiency), making it ideal for spaceships.


Nitrogen and Helium are inert gases; they are often used to pressurize fuel tanks but do not burn as fuel.


Carbon Dioxide is a product of combustion and cannot be used as a fuel itself.


Therefore, option (A) is the correct answer.
Quick Tip: Liquid Hydrogen is the signature fuel of the American space program, used in the Saturn V and the Space Shuttle Main Engines. It is stored at an extremely low temperature of -253°C.
