D is wrong. B is correct. the d-orbital cannot be filled before the s-orbital since it is a higher energy level.

electrons are filled in order of increasing orbital energy

D . is the right answer when filling transition metals the 3d orbital is firstly filled before the 4s orbital.

Option'D' should be the correct answer, because for transition metals, electrons are fed into second to the last shell before the outermost shell.
If it is in its ground state, option'A' should be the answer but since it has loss 3electrons, the correct answer is Option'D'.

Option D is correct simply simple due to the stability associated with the d5 configuration
