Explanation:
When sodium butanoate is heated with soda lime, it undergoes a decarboxylation reaction to form an alkane. This is a type of organic reaction in which a carboxylic acid loses a carbon atom from the carboxyl group as carbon dioxide.

The reaction can be represented as follows:
CH3CH2CH2COO-Na+ + NaOH → CH3CH2CH3 + Na2CO3

Here, sodium butanoate reacts with sodium hydroxide (NaOH) in the presence of soda lime (NaOH + CaO) to form an alkane, which is propane. Sodium carbonate (Na2CO3) is also formed as a byproduct.

Therefore, the correct answer is option C, propane.
