How to reset the value of the radio buttons?

Hello!
I am using this in a project and I am stuck! 

I am looking for a way to reset the radio options (I have 2 radio buttons and I want both of them de-selected) when lets say a user selected Option A from a picker. How do I do that using functional components? Any help is much appreciated as not having this work is becoming a deal-breaker for me. 

Thanks in advance
