Without looking at your code, just on the theoretical…

You would need to keep track of the id of which one is selected. This could be in the component state, some lifted up state, redux state, context, whatever. You would set it when something is pressed and change it when something else is pressed and clear it if needed. This value would be passed into whatever is rendering your choices so each choice would know which CSS/class to use.
