Correct Answer - A::B
In the given reaction, alkyl halide is primary in nature. Here, a transitory state is observed in which one bond is broken and one bond is formed synchronously i.e., in one step. So, it follows `S_(N)2` mechanism.
In this mechanism, nucleophile attacks the carbon at `180^(@)` to the leaving group, so the reactant and product have opposite configuration.
