How do I make a UI selection menu?

Hi,

I am working on a mobile application and I am currently trying to figure out how to make a selection list UI for a specific scene.

How do I make multiple buttons and when you select one, the button remains selected (or checkmarked) forever until I select another?

Also, how do I make the selected button affect the outcome for this different button which is placed in a different scene?
