Answer:
B. Speaker of the House
Step-by-step explanation:
The speaker of the United States House of Representatives assumes the functions of representing the House of Representatives. He usually does not preside over the debates personally, instead he delegates this function to another member of the majority party chamber. In addition to presiding over the chamber, he has administrative and procedural functions, and remains a representative of his own district.
It occupies second place in the line of presidential succession, 1 after the vice president of the United States who also assumes ex officio the presidency of the Senate.
