Correct answer
2

Step-by-step explanation

FeCN63- In this the central metal Fe is in +3 oxidation state. And CN- is strong field ligand so, it will form inner orbital complex.

Electronic configuration in Fe3+: d5

Electronic configuration for inner orbital complex: t52g e0g

CFSE=5-0.4Δ0=-2.0Δ0

So, final answer will be =2
