An aqueous solution of a salt X turns blood red on treatment with $SC{N}^{-}$ and blue on treatment with ${K}_{4}[Fe{(CN)}_{6}]$ , X also gives a positive chromyl chloride test. The salt X is:

After understanding the assertion and reason, choose the correct option. Assertion: In the bonding molecular orbital (MO) of ${\text{H}}_{2} ,$ electron density is increased between the nuclei. Reason: The bonding MO is ${\text{ψ}}_{\text{A}}+{\text{ψ}}_{\text{B}}$ , which shows destructive interference of the combining electron waves.

The ionic radii $(\text{in} Å)$ of ${N}^{3-}, {O}^{2-}$ and ${F}^{-}$ are respectively:
