(a) Both assertion and reason are correct and the reason is correct expansion to assertion. (b) Both assertion and reason are correct but reason is not the correct expansion of assertion (c) Assertion is correct but reasion is wrong (d) Assertion is incorrect but reason is correct. Q. Assertion: `Phoverset(c+)(N)_2Br^(Theta)` on reaction with nitrobenzene in the presence of `NaOH` gives p-nitro biphenyl. Reason: The reaction takes place by free radical mechanism.
