(B) The electronic configurations of the given elements in their ground state are:${}_{25}Mn = [Ar] 3d^5 4s^2$ (Number of unpaired electrons = $5$)${}_{24}Cr = [Ar] 3d^5 4s^1$ (Number of unpaired electrons = $6$)${}_{28}Ni = [Ar] 3d^8 4s^2$ (Number of unpaired electrons = $2$)${}_{26}Fe = [Ar] 3d^6 4s^2$ (Number of unpaired electrons = $4$)Comparing these,${}_{24}Cr$ has the highest number of unpaired electrons,which is $6$.
