Solution

The correct option is D $P h - O | | C - N H - C H_{3}, C H_{3} - O | | C - N H - P h$
As refer to IMAGE $01$ , in this reaction group anti to $- O H$ group will migrate. This is called as Beckmann rearrangement of oximes to give amide.
Refer to IMAGE $02$ , Same mechanism as that in $(A)$ . Here antigroup to $- O H$ group is $- P h$ , so $P h$ will migrate, rest mechanism is same.
