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.

The 4s orbital is at a higher energy level than the 3d orbitals and so because it is Fe(2+) the two electrons both leave the 4s orbital, leaving the 3d orbital with 6 electrons. And so:
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).

Thanks for answers. The number of d-electron in fe2+ is not equal to that of p-electron in cl.

After seeing explains, I don't think any other explanation is required.

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.

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

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.

Actually half filled and full filled orbital are much more stable than partially filled orbital, that is why fe will first loose one electron from d orbital to half filled the 3d orbital then loose one other electron from 4s orbital and become more stable.
