What should I mention? For laid off!

But see if any organisation ask for Releving later. In that resignation and releving date is same as well as i also received 3 months of salary.

No bad idea. The best response would be "got laidoff due to business reasons". Based in the gap time line you can build your BS story. If the gap is more than 6 months, claim you wanted to use this opportunity to learn something new,/upskill. If it becomes more than a year. the BD should be you started your own business and the business failed..

The golden rule of lying - Always start with the truth.
