Which of the following is a cabinet-level position?

The Secretary of Commerce is a cabinet-level position because this role is part of the President's cabinet, which is composed of the heads of the executive departments of the federal government. The Secretary of Commerce is responsible for promoting American business and ensuring that the interests of consumers and businesses are represented. This position involves advising the President on issues related to commerce, trade, and economic growth, working in collaboration with other cabinet members to implement the administration's policies.

In contrast, the Speaker of the House is a legislative leader in Congress, and the Senate Majority Leader is also a legislative position, directing the operations of the Senate. The Chief Justice of the Supreme Court leads the judicial branch and is not part of the executive cabinet. Each of these positions plays a vital role in the U.S. government but operates within different branches or levels of authority.
