hi guys.. what plugin is this? please help. if available in here please share link. thanks a lot.

It's not a plugin, it's a default setting.

Go to admin center > settings > downloads > categories. In the settings of each category there is an item "display" > download conditions, write your rule there.

To make it easier, here are some screenshots.
