How can I allow just one input selection in react?

Question

Right now only one selection is allowed between all inputs. I'm not sure how to solve this. I thought the name was supposed to match between all inputs, but perhaps I'm wrong. If I remove it, then there is an endless number of input selections allowed.

How can I fix this? Thank you.
