Querry Regarding Option Selling

I have never practically done this and have a query.

Nifty is at 9108 right now. If I sell call of 9200 of March 1 Lot, then what will happen to my position on last Thursday if the market closes below 9200.

PS - I know it will go to 0.05 but is there any other side effect or thing I don't know if I hold it to closing i.e. 3:30 pm.

Another case. Reliance is at 1286. What if I sell call of 1350 and on Thursday price closes below 1350 and I keep holding my position till expiry.

Simple answer, please.

My point is, that I am assuming that I can see the price is not going above lets say 9200 or 1350 incase of reliance. So even if I do not close my position (buy at the price .05) and let it expire, would I get any penalty or would be asked to sell at that price as it is option and I am selling. Or I can simply assume that next day I will have profit +premium in my account even when i let it expire and never closed it. Thats my querry.

So just confirming.

1. I can let it expire worthless without needing to worry about any penalty from exchange as I dont have the underlying stock in demat ?

Or I can cover it at 0.05 and in everycase its a win win situation.

2. Sometimes we get lucky or unlucky to sell a non liquid option contract. In that case also if the price stays below the strike, it will expire and I will be in profit ?
