The correct answer is: A. SelectedText
The SelectedText property of a ComboBox control contains the text of the item that is currently selected in the list.
The SelectedValue property contains the value of the item that is currently selected in the list. The value is the data that is associated with the item, not the text of the item.
The Text property contains the text that is displayed in the ComboBox control. This is not necessarily the same as the text of the selected item.
The TextItem property is not a valid property of a ComboBox control.
