I know only cash, what should I buy in future and options if I am sure that BJP has high chances of loosing on 4june

I have 20K, I have made profits in the past using investing. I am ready to loose 20K + taxes.

Just tell me the thing I want to buy if I believe that BJP will not win.

I have an idea that it will be a put, but there are many puts and I don't understand them.
