Future & Option Expiry day delivery when turned to ITM

Hi people,
I took one of the trade of future expiry tomorrow 200CE which was priced 0.55paisa …tomorrow is expiry…it’s stock price is 193

So example tomorrow market opens at 197 and touches 200 205 opening time then do my future calls become ITM.

I don’t have any margin available now…
Some are saying I should have margin else penalty will be charged…

What I planned is tomorrow when market opens will sell that at 1 rs max or whatever price it is at.
so will that be fine?

I have taken risk…I am using dhan platform for trading…so please can anyone explain me here…
