Which of the following are Cabinet-level positions?

The correct answer is that all of the mentioned positions are indeed Cabinet-level positions. In the United States, the Cabinet is composed of the Vice President and the heads of the executive departments, which include various secretaries.

The Secretary of Transportation manages federal transportation policies, the Secretary of State oversees the country's foreign affairs, the Secretary of Agriculture focuses on farming and food policies, the Secretary of Commerce is responsible for promoting economic growth, and the Secretary of Education oversees federal education programs. Each of these roles is crucial in advising the President and implementing governmental policies.

Every option listed includes secretaries who are part of the Cabinet, as well as the Vice President, who, while not a departmental head, is part of the Cabinet. This comprehensive inclusion of both department heads and the Vice President in the answer supports its correctness, illustrating that these positions form a vital part of the executive branch of the government.
