Hund's rule.

Hund's rule states that when filling orbitals of equal energy, electrons occupy them singly and with parallel spins before pairing up. The given electron configuration 1s² 2s² 2p²x does not follow this rule, as the 2p orbitals should be filled with one electron each before pairing up.

option D is correct
