.The electronic configurations are as follows;

V:(Ar)3d34s2V:(Ar)3d34s2

Cr:(Ar)3d54s1Cr:(Ar)3d54s1

Mn:(Ar)3d54s2Mn:(Ar)3d54s2

Fe:(Ar)3d64s2Fe:(Ar)3d64s2

The second ionization of CrCr means removal of electron from the stable configuration of 3d53d5.

The highest second ionization enthalpy is CrCr

Hence b is the correct answer.
