I think the answer is B because, when its Mg=12, it is 1s2 2s2 2p6 3S2 but the Fe=26 is 1s2 2s2 2p6 3s2 3p6 4s2 3D6.
Even after you lose one electron from the 'd' of Fe orbital it still is not equal to that of Mg.

No.of d electrons Fe+2 6(3d6)
no.of p electrons in Ne is 6(2p6),
no.of s electrons in Mg is 6(1s2,2s2,3s2)
no.of d electrons in Fe is 6 (d6)
no.of p electrons in Ci is 11(2p6,3p5)
no.of p electrons in Ne is 6(2p6),
no.of s electrons in Mg is 6(1s2,2s2,3s2)
no.of d electrons in Fe is 6 (d6)
no.of p electrons in Ci is 11(2p6,3p5)

I think option C is right.
Since outer most electron that is in the d orbital there number are 10 and also Fe2+ (Z=26) that's outer most electron numbers are 10 in d orbital.

1s2 2s2 2p6 3s2 3p6 4s2 3d6 is Fe electronic configuration.
While Cl is having 1s2 2s2 2p6 3s2 3p5, so Fe2+ is having configuration as below 1s2 2s2 2p6 3s2 3p6 4s0 3d6.

The question should be stated like this:
"The number of d-electrons in Fe2+ (Z = 26) is equal to that of"
The word "not" should be omitted.
"The number of d-electrons in Fe2+ (Z = 26) is equal to that of"
The word "not" should be omitted.

Neon is a gas (group 8), Valence electron - 2. Mg and Friday are electro positive metals +2. Click is not equal because it has - 1(2, 8 7). The answer is done.

But I think the question is incorrect, as it asked.
It should be, The number of d-electrons in Fe2+ (Z = 26) is equal to that of.
It should be, The number of d-electrons in Fe2+ (Z = 26) is equal to that of.

P electrons of Ne-2p6, s electron of Mg-3s2, d electron of Fe-3d6 but p electron of Cl is 3p5. So answer may be option D.

I think the answer is correct because after D, orbital looses their one electron it stabilised fully.
