The correct answer is the country supervisor or the District Election Board.
The two members of the election board are selected by the country supervisor or the District Election Board.
The country supervisor function during an election is to supervise the process in all the counties that belong to the state. The District Election Board is an independent agency responsible for the administration of elections. SO it is correct to say that the two members of the election board are selected by the country supervisor or the District Election Board.
