Which method would you use to determine if a radio button is selected in Selenium?

• A. isVisible()
• B. isChecked()
• C. isEnabled()
• D. isSelected()

Answer: (D)

The method to use for determining if a radio button is selected in Selenium is the one that accurately reflects the state of the element in question. In this case, the appropriate method is to use isSelected().

When dealing with input elements like radio buttons (where only one option can be chosen from a set), isSelected() checks whether the specific radio button is currently selected or not. It returns a boolean value: true if the radio button is selected and false if it is not. This method specifically verifies the state of selection which is crucial for validating user interactions in practice scenarios involving forms or choices.

The other options do provide useful checks for different scenarios but do not serve the purpose of determining selection status for radio buttons. isVisible() checks if an element is present and displayed on the page, isChecked() is not a standard Selenium method (though it conceptually aligns with checkbox states), and isEnabled() checks if the element is enabled for interaction but not specifically its selection state. Thus, for ascertaining whether a radio button is selected, isSelected() is the correct choice.
