If both assertion and reason are true, but reason is not the true explanation of the assertion
If both assertion and reason are true, but reason is not the true explanation of the assertion
If assertionis true, but reason is false
If both assertion and reason are false

Solution :Correct explanation. The colour of the complex formed, `[Fe(H_(2)O)_(5)NO]^(2+)` is DUE to charge TRANSFER (transfer of odd `E^(-)` on N to Fe, CHANGING NO to `NO^(+)` and `Fe^(2+)` to `Fe^(+)`).
