What is a radio button control as used in VB NET?

A radio button control in VB.NET is a graphical control element that allows the user to select one option from a set of mutually exclusive options. When a radio button is selected, all other radio buttons in the same group are automatically deselected. This allows the user to choose only one option at a time. Radio buttons are commonly used in forms and dialog boxes to present a list of options for the user to choose from.
