Answer: B [Methane ]

Notes:

Methane is a saturated hydrocarbon. Its chemical formula is CH4. It is the main constituent of natural gas. Also, refined liquid methane is used as a rocket fuel. Use of Methane based rocket is currently in trend and SpaceX uses pure methane. Propane has inherent properties such as large mass and need of very low cooling point due to which it is not used as rocket fuel.
