Which of the following statements correctly describes the etiquette in America？

A、In General Election, people vote for who they wish to be elected as the MP for their local area. The person who receives the most votes is appointed in the role for up to five years. Typically the political party who receives the most number of seats in the House of Commons forms the government. The leader of the political party who wins will be made the President of the U.S.A.

B、In General Election, 16 states are subdivided into 299 districts, each containing roughly 250,000 eligible voters. On election day, voters receive a ballot divided into two columns. On the right side of the ballot, voters choose the candidate they would like to represent their district in the parliament. On the left side of the ballot, voters choose the party they feel best represents their interests. After multiple rounds of votes, the party that has the most representatives in the parliament usually determines who will be the next President.

C、The election of President is an indirect election in which the citizens who are registered to vote in one of the 50 states or in Washington, D.C. cast ballots not directly for those offices, but instead for members of the U.S. Electoral College, known as electors. These electors then in turn cast direct votes, known as electoral votes, for President. The candidate who receives an absolute majority of electoral votes is then elected to that office.

D、The President is designated by both houses of the parliament, before the conduct of any other business. For that purpose, each conducts a ballot under the run-off system. If the two houses choose different individuals, then a joint committee of both houses is appointed to agree on a common candidate. Ultimately, however, if the two houses do not agree within 10 days, the decision of the House of Representatives is deemed to be that of the parliament. Therefore, the House of Representatives can theoretically ensure the appointment of any President it wants. The candidate is then presented with his or her commission, and formally appointed to office by the Emperor.
