Radio button in an interface is labeled using . . . . . . . . property.

The correct answer is: D. Label

A radio button is a type of button that allows the user to select one of a set of mutually exclusive options. The label of a radio button is the text that appears next to the button and describes the option that it represents. The label is used to help the user understand what the button does and to select the correct option.

The other options are incorrect because:

• Text is the general term for any text that appears on a user interface. It can be used to label buttons, text boxes, and other elements. However, in the specific case of radio buttons, the text that appears next to the button is called the label.
• Caption is a term that is sometimes used to refer to the label of a radio button. However, this term is more commonly used to refer to the title of a window or dialog box.
• Name is the unique identifier for a radio button. It is used by the program to refer to the button and to store its value. The name is not displayed to the user.
