Citizens who are legally qualified to vote are referred to as the electorate. This means that they have met the legal requirements to participate in the electoral process, such as being of a certain age, being a citizen of the country, and being registered to vote. The electorate is responsible for choosing representatives to serve in government through the electoral process, which includes voting in elections. The other options listed, such as political parties, Trade Union Congress, Members of the House of Assembly, and a ward, are not equivalent to the electorate.
