Take for example June expiry of HInd Unilever-

On Jun25th closing price of Hindustan Unilever-

Equity- 2156.5

Future- 2153.9

2100 call option- Last traded price was 60

So, if i hold 2100 call option which was left to expire, what will be the settlement price of my Call option?

is it on underlying price in that case 56.5 or on last traded price of call option which is 60?
