Correct answer
B.
Step-by-step solution
The first step involve the fridel craft alkylation reaction of benzene and cummene is formed as the product. That on oxidation with oxygen gas gives phenol and acetone.
Oxidation of phenol with strong oxidising agent will give benzoquinone(A). And bromination of phenol in non-polar medium will give ortho or para bromo phenol as major product.
