SN2 reaction at asymmetric carbon means the Nucleophilic substitution through the formation of transition state occurs at the chiral carbon in the compound. The leaving group is then pushed off the opposite side and the product is formed with inversion of the tetrahedral geometry at the central atom. Hence, it will have opposite optical rotation. option C leavo product

option C is correct. The SN2 reaction - A Nucleophilic Substitution in which the Rate Determining Step involves 2 components. -SN2 reactions are bimolecular with simultaneous bond-making and bond-breaking steps. -SN2 reactions do not proceed via an intermediate. -SN2 reactions give inversion of stereochemistry at the reaction centre.
option A is given incorrect because in SN2 always inversion takes place
