How can you enable or disable an input field in Reactjs based on the selection of a radio button?
This Reactjs code snippet creates a form with three radio buttons and corresponding input fields. The input fields are enabled or disabled based on the selected radio button. The component uses the useState hook to manage the selected option state.
