Which element has the same number of energy levels as aluminum (Al) and the same number of valence electrons as calcium (Ca)

Ithinks its false. tell me if im wrong

The answer is c) pyrite

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.
