C Correct answer
Explanation

The DropDownList control in ASP.NET uses the SelectedIndexChanged event to detect when a user selects a different item. This event fires after the selection changes and the page posts back. The Click event (option A) is for button controls, and the other options are invented names that don't exist in the DropDownList control's event model.
