AIIMS 2019 Chemistry Carbocation Rearrangement MCQ Question

Option B is correct because it represents the final product formed after a carbocation rearrangement, where a more stable tertiary carbocation is generated, leading to the formation of a more substituted alkene through elimination. The other options are incorrect as they either depict intermediates that do not reflect the final product after rearrangement or show products that lack the necessary stability or structural features expected from the reaction sequence. Understanding carbocation stability and the mechanism of elimination reactions is crucial in predicting the major product in organic synthesis.
