yes you can hold shorted option call till expiry if you want if you maintain margin, exchange will settle.

can u please explain me how to calculate margin required for shorting option like this
n if my desired price does not hit till exp what will happen if i dont execute it on exp date

margin you can check in span calculator, if you are shorting option you require complete margin…i think… at expire will be settled by exchange if not cleared position.
