AIIMS 2018 Chemistry Oxidation Reactions MCQ Question

Option B is correct because it represents the major product formed through the specific reaction mechanism, which likely involves nucleophilic substitution or elimination, leading to the desired functional group transformation. The other options are incorrect as they do not correspond to the expected reaction pathway or fail to account for the regioselectivity and stereochemistry involved in the formation of the major product. Understanding the reaction conditions and the stability of intermediates is crucial for predicting the outcome of organic reactions, as these factors influence which product predominates.
