Which of the following best describes a major role of the Department of Homeland Security?

The major role of the Department of Homeland Security (DHS) is centered around preparing for and recovering from domestic incidents. This includes responding to natural disasters, terrorist attacks, and other emergencies that could jeopardize the safety and security of the United States. The agency's mission encompasses a wide range of activities, such as disaster response coordination, emergency management, and securing the nation's borders.

DHS focuses on creating strategies to prevent incidents and mitigate their impacts, promoting resilience within communities, and ensuring that the country is prepared to handle various types of threats, both man-made and natural. This proactive management of risks and emergencies is a core component of what the department is designed to do.

In contrast, managing federal healthcare programs pertains more to agencies like the Department of Health and Human Services. Economic growth is typically influenced by various federal and state agencies, including the Department of Commerce, but it is not the primary focus of the DHS. Oversight of state educational standards falls within the purview of the Department of Education, which manages policies and programs related to education. Thus, the responsibilities of the DHS are distinctly aligned with incident preparation and recovery, making the correct choice the most appropriate answer regarding its role.
