Which of the following is a responsibility of the federal government?

The responsibility of the federal government to provide national defense is rooted in the Constitution, which establishes the federal government’s role in protecting the country and its citizens from external threats. This function includes maintaining the armed forces, managing military operations, and ensuring the safety and security of the nation. This overarching duty emphasizes the importance of a centralized authority in safeguarding against foreign aggression, making it a core function of the federal government.

In contrast, conducting state elections, regulating local businesses, and managing public schools are primarily responsibilities of state and local governments. Each of these areas involves governance and regulatory powers that fall under state jurisdiction, reflecting the distribution of powers outlined in the federal system. The Constitution grants states the authority to administer their own electoral processes, oversee local businesses according to local needs, and manage public education systems tailored to their communities.
