Best answer
Right answer is (b) Scandium, Zinc

The best explanation: In the 3d transition series, the have either partially or fully filled 3d orbitals. The 3d transition state starts from Scandium (Z = 21) having electronic configuration as 3s^23d^1 and ends with Zinc (Z = 30) whose electronic configuration is 3s^23d^10.
