Assertion : The purple colour of KMnO_4 , is due to the charge transfer transition. Reason : The colour of most of the transition metal complexes'is due to d-d transition. a)If both (A) and (R) are correct and (R) is the correct explanation of(A). b)If both (A) and (R) are correct, but(R) is not the correct explanation of (A). c)If(A) is correct, but (R) is incorrect. d)If both (A) and (R) are incorrect.
