Liquid hydrocarbons can be converted to a mixture of gaseous hydrocarbons by

  • oxidation

  • cracking

  • distillation under reduced pressure

  • hydrolysis

Answer

B.

cracking

Lower hydrocarbon exists in a gaseous state while higher ones are in liquid state or solid state.
On cracking or pyrolysis, the hydrocarbon with higher molecular mass gives a mixture of hydrocarbons having lower molecular mass. Hence, we can say that by cracking a liquid hydrocarbon can be converted into a mixture of gaseous hydrocarbons.
