The number of d electrons retained in Fe²⁺ (Z of Fe=26) ion is 4.
You have doubt that how it is can derived .
The electron configuration for Fe2+ will be 1s2 2s2 2p6 3s2 3p6 4s2 3d4 for the finally the answer will be 4.
Hope it will be right option for the student to get an ideas among them with no risk and trouble of it.
