B
If both assertion and reason are true but reason is not the correct explanation of assertion
C
If assertion is true but reason is false

Answer
If both assertion and reason are true and reason is the correct explanation of assertion
Explanation
Solution
Fe : [Ar] 3d 4s When the weak field ligand HO and strong field ligand NO attack, the configuration changes as follows: Fe : [Ar] 3d 4s ? Fe has 3 unpaired electrons.
