Answer:
D) the number of people who registered to vote in the election
Explanation:
The official attendance of an election is calculated by dividing the total number of people who voted by the number of people who registered to vote in the election.
The number of people who registered to vote in the election includes the number of people who are members of political parties, the number of people eligible to vote (since these people also vote) and the number of ordinary citizens who voted.
The number of people in the general population is not considered because it is not the entire population that votes, for example, children and immigrants although they are part of the population, they do not have the right to vote, so it is irrelevant in an election that the number of people in the general population is counted
