The method GetText of the Clipboard class should be used to retrieve the contents of the Clipboard and assign it to the SelectedText property of txtBox. This will replace the currently selected text with the contents of the Clipboard. Option A is close but wrong, as it needs to use the GetText method. Options B and C are also incorrect as they use the SetText and Clipboard classes directly, which do not properly retrieve the content of the Clipboard.
