b. the president of the United States
c. the chief justice of the U.S. Supreme Court.
Explanation:
The two offices that are part of the federal government are the president of the United States and the chief justice of the U.S. Supreme Court.
The President of the United States is the head of the government of the United States and is the commander-in-chief of the armed forces. The President is responsible for executing laws, making treaties, appointing federal officers and ambassadors, and nominating federal judges.
The Chief Justice of the U.S. Supreme Court is the head of the judicial branch of the federal government. The Chief Justice presides over the Supreme Court, ensures that the court's rulings are unbiased, and is responsible for managing the court's day-to-day operations.
