- C

- D

View written solutionFree
Correct answer: C
The intermediate is carbocation which is destabilised by C = O group (present on - carbon to the –OH group) in the first three cases. In (c), –hydrogen is more acidic which can be removed as water. Moreover, the positive charge on the intermediate carbocation is relatively away from the C = O group.
