Solution

The correct option is B The Assertion is true, Reason is true and Reason is NOT the correct explanation for Reason
The reactivity of borazole is higher than the reactivity of benzene as the resonance structures in borazole contain dissimilar atoms which results in lower stability. In borazole, the nitrogen atom donates electrons to the electrophile.
Hence, The Assertion is true, Reason is true and Reason is NOT the correct explanation for Assertion
