Which of the following is a Java callback method invoked when a view is clicked?

The correct answer is C. onClick.

Explanation: The `onClick` method is a callback method that is invoked when a view, such as a button, is clicked in Java (specifically in Android development). To implement a click action, you typically set an `OnClickListener` on the view, which references the `onClick` method to define what happens when the view is clicked.
