If your position is options buying and it is supposed to be under the ITM option, then you need to square off your position. otherwise, you should be eligible to buy equal qty of cash by physical delivery (Google the physical delivery of ITM option).
In such case, you don't have enough amount in your T Account, then zerodha helps you by square off your ITM position by themselves. Otherwise, a huge penalty will be imposed to you by NSE as per Sebi physical settlement rule.
If the above case is not applicable to you, then pls ignore my statement.
