Solution
The correct option is A Both Assertion and Reason are true and Reason is the correct explanation of Assertion This decolourising of bromine water is a test for unsaturated compounds.
Due to delocalisation of pi electrons benzene doesnt give test of unsaturation and doesnt undergo addition reaction. (As aromatic system is most stable)
