Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The Gabriel synthesis is a chemical reaction that transforms primary alkyl halides into primary amines. Traditionally, the reaction uses potassium phthalimide. The reaction follows $S_{N} 2$ mechanism. Presence of $- N O_{2}$ an electron withdrawing group at -para position stabilizes the nucleophilic anion.
