Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
$S_{N} 2$ reaction is carried out in the presence of a polar aprotic solvent.
In the presence of a polar solvent, the formation of carbocation is easy. Polar solvent helps in the dissociation of C-X bond where X is the leaving group.
Polar protic solvent increases the stability of carbocation due to solvation.
Hence, Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
