There can be 1,2 - aryl shift also bro. (not in this question but as a fact)I dont feel that ethyl cant shift ..
In pinacol -pinacolone rearrangement dont we shift it?
Migratory aptitude also has a significant role in shifts imo and in fact general trend is that. Bulkier groups have more migratory aptitude
No bro @pratyaksh_tyagi The answer is the one we get by 1,2 -alkyl shift(ethyl) in the last step..
