Using Multiple Radio Buttons in C# Groupbox and Printing the Selected One from Database

[GoldenPlaya3]

Hello, I hope you're doing well. I have multiple group boxes and radio buttons as seen in the picture, and I want to print the name of the selected one by retrieving it from the database. However, I'm unsure about which query method to use for this. Can you help me with this? I want it to write the selected one to the database using an if loop.
