I think the correct answer from the choices listed above is the third option. It is the Speaker of the House that has the power to lead the caucus and control the agenda. The Speaker of the House is the presiding officer of the United States House of Representatives. Hope this answers the question.
The correct answer is the Speaker of the House.
The Speaker of the House is an individual from the majority party in the House of Representatives. This person oversees the actions taking place on the floor at the House of Representatives and has power to control the agenda. This person is also important because they are in the line of succession for the presidency. If the president and vice president become incapable of acting as president, the Speaker of the House takes over the responsibility of being president.
