Hello aspirant!
Hope you are doing well!

You would be happy to know that you can cancel the seat, which you have received in Mop-up round, if you don't like it.
The security money will be refunded only if you are not allowed a seat after the stray mop-up round and if you take admission in a seat allotted by MCC, the amount will be adjusted with your first-year fees.

Hope this helps!
