Why was the settlement price 0 for the option position, although the Last Traded Price (LTP) is not 0?

The settlement price is based on the weighted average price for the last 30 minutes in the cash market for the underlying instrument. It’s important to note that the Last Traded Price (LTP) cannot be zero. However, if the option’s strike price is Out-of-The-Money (OTM), the settlement price will be zero, regardless of the LTP price.
