Answer will be C & D both.
Since Fe²+(26) have total d - electron = 6.
In Cl(17) Total p- electron = 11, that is not equal to 6 ( Fe²+)
Also Fe(26) have total d- electron = 8, not equal to that of Fe²+.

Fe+2 = 1s2,2s2,2p6,3s2, 3p6,4s1,3d5
or 1s2,2s2,2p6,3s2, 3p6,4s2,3d4
Cl = 1s2,2s2,2p6,3s2, 3p5
Fe = 1s2,2s2,2p6,3s2, 3p6,4s2,3d6
Mg = 1s2,2s2,2p6,3s2
Ne = 1s2,2s2,2p6

Question is about {not equal d-electrons}
d-electrons are only present in Fe and Fe+
given answer in wrong

Fe2+ = 1s2 2s2 2p6 3s2 3p6 4s2 3d4
but cl = 1s2 2s2 2p6 3s2 3p5
how is this right answer?

Electronic Distribution for
Fe (26) ...... 3d 8 but Fe+2 (24) ....... 3d 6
Ne (10) ....2p 6
Mg (12) ...3s 2
Cl (17) ...3p 5
The Correct Answer is : A. p-electrons in Ne(Z = 10)

write out the electron configurations.

Fe2+ has no electrons in d orbitals and neither does Cl.
