Quizplus · Accepted Answer

The reaction is a nucleophilic substitution reaction in which a primary alkyl halide reacts with sodium iodide in acetone. This reaction is known as a Finkelstein reaction. In this reaction, the iodide ion acts as the nucleophile and replaces the leaving group (bromine). As a result, the product formed is an alkyl iodide. 
Here, the given compound is a primary alkyl bromide, and sodium iodide is a better nucleophile than bromide ion. Therefore, the product formed will be 1-iodobutane (III). Hence, the correct answer is option C.
