No, the option buyer is only able to exercise their right upon the contract's expiry.
For instance, Ms. Mehta acquires a put option for Bajaj Auto with a ₹3,000 strike price, set to expire in three months. Even if Bajaj Auto shares drop to ₹2,900 within the first month, Ms. Mehta cannot exercise her selling right at the strike price until the pre-specified expiry date.
