Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R) :
Assertion (A) : $S _{ N } 2$ reaction of $C _6 H _5 CH _2 Br$ occurs more readily than the $S _{ N } 2$ reaction of $CH _3 CH _2 Br$.
Reason (R) : The partially bonded unhybridized p-orbital that develops in the trigonal bipyramidal transition state is stabilized by conjugation with the phenyl ring.
