Explanation:

The members of the United States Congress -the bicameral legislature that includes two chambers, the House of Representatives and the Senate- share responsibility for the lawmaking process within the United States. Although senators and representatives are elected by direct popular vote, senators are elected through a statewide vote and representatives are elected by the voters of the particular congressional district they represent. Therefore, sentence A is the correct answer.
