In case of Richa and Smita, judges did not praise them properly and they had criticized them for their previous performances...so they took their own name when they were asked.
In case of Ankita..All judges praised her and nobody criticized her while Emon was praised by only Alisha.
So why will she take her name she will think I guess I was better?
Anyways.. now tum apne aap ko Ankita ke position me rakho aur answer karo. But I know your answers. So no need to answer and understand.
