Text Solution

Verified by Experts

The correct Answer is:
A
This is an example of Benzil-Benzilic acid rearrangement reaction. `overset(Θ)(OH)` attacks at the more reactive `(C=O)` group, (containing more EWG or less EDG). Et is more EDG than Me (due to +I effect, here no H.C.). Therefore, `overset(Θ)(OH)` attacks `(C=O)` with (Me)group.
