Zn, bcz it has fully filled stable d orbital so it only shows +2 oxidation state. On the other hand, Sc shows mostly+3 oxidation although it also shows +2 but in very rare cases. That's why, C would be the best answer.

Zn because “Zn has a stable, completely filled 3d¹⁰ configuration, so it shows only +2 oxidation state.”
