Best answer
The correct option is (a) methane

To explain: Sodium acetate undergoes decarboxylation (loss of CO2) when heated with soda lime. This is proceeded by the loss of COONa from the sodium salt and NaO from sodium hydroxide. They combine to form CH4 and Na2CO3. The hydrocarbon formed has one less carbon atom than the parent acid.
