Solution

The correct option is A n- propyl chloride
Wurtz reaction is a coupling reaction. The alkyl groups of reactants get doubled on coupling.
So, n-hexane will be obtained by n-propyl chloride.
$2 C H_{3} - C H_{2} - C H_{2} - C l + 2 N a \to C H_{3} - C H_{2} - C H_{2} - C H_{2} - C H_{2} - C H_{3} + 2 N a C l$ .
Hence option A is correct.
