(A) The electronic configurations of the given elements are:$Ti (Z=22): [Ar] 3d^2 4s^2$ (Unpaired electrons = $2$)$V (Z=23): [Ar] 3d^3 4s^2$ (Unpaired electrons = $3$)$Cr (Z=24): [Ar] 3d^5 4s^1$ (Unpaired electrons = $6$)$Fe (Z=26): [Ar] 3d^6 4s^2$ (Unpaired electrons = $4$)$Sc (Z=21): [Ar] 3d^1 4s^2$ (Unpaired electrons = $1$)Thus,$Cr$ has the maximum number of unpaired electrons.

The number of unpaired electrons is maximum in (Atomic no. : $Ti = 22; V = 23; Cr = 24; Fe = 26$)
