AIIMS 2019 Chemistry Reaction Mechanisms MCQ Question

Option B is correct because it represents the final product formed after the specified reaction sequence, which likely involves key transformations such as functional group interconversions or rearrangements. The other options are incorrect as they either depict intermediates that do not correspond to the final product or represent products formed under different reaction conditions that do not align with the sequence provided. Understanding reaction mechanisms and the stability of intermediates is crucial in predicting the correct product in organic synthesis.
