The numberical values of `(N)` and `(M)` are `:`

Options

A. 6,6
B. 6,4
C. 4,4
D. 3,3

Answer

B

Explanation

In these, `(iii)` and `(iv)` are enantiomers and `(v)` and `(vi)` are also enantiomers to each other. Thus, total six isomers will be possible for `N`. In these,only four isomers will be obtained on fractional distillation without resolution because `d` and `l` isomers `[i.e., (iii),(iv), (vi)]` cannot be separated by fractional distillation. Hence, `N=6` and `M=4`.
