Once the stock resumes trading (most likely, OTC), you can exercise your puts. You can buy the stock (let's day, for 5 cents), and exercise them at your put strike price. Most likely you will make more money by exercising than selling (OTC might be illiquid).
As a put holder, you are guaranteed the stock sale at the strike price by the Options Clearing Corporation, regardless of the company bankruptcy. So, hold on to your puts, they are worth good money. Congrats.
