Mispricing of option price?

Today Nifty closed at 5315. But 5300CE Aug option closed at 8.1
Shouldn't it be around 15, because time value is 0 and intrinsic value is 15. How is it possible that the closing price coming at 8.1? is it a miscalculation by NSE?

'Closing' price of Nifty can be different from 'Last Traded Price'.

As it is the expiry day, Closing price means the settlement price. But it should be 15.

Seems like you haven't got question properly.

Nifty futures closed at 5306. So it baffles me more because the options are derived from the futures. So, the closing price should be (Rs. 6 - expenses) = around Rs. 2
