The major product of the reaction is: ABCD?

When an aliphatic primary amine is treated with NaNO2 and HCl, an unstable aliphatic diazonium salt is obtained which decomposes to form an alcohol with liberation of nitrogen gas. The reaction is shown above. Here the reaction goes through an SN2 (Inversion + Inversion) mechanism, so a retention product is obtained. Option C is correct.
