Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
The isopropyl benzene results from a rearrangement of the initially formed propyl carbocation to the more stable isopropyl carbocation.

Benzene is an electron-rich species. It undergoes electrophilic substitution easily.
So Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Hence option B is correct.
