The US federal agency with a mission to protect human health and the environment?

• A. Federal Communications Commission
• B. National Aeronautics and Space Administration
• C. Securities and Exchange Commission
• D. Environmental Protection Agency

Answer: (D)

The agency dedicated to safeguarding human health and the environment is the Environmental Protection Agency. This agency focuses on protecting people from environmental risks and reducing pollution by setting and enforcing standards, conducting research, and enforcing laws related to air and water quality, hazardous waste, pesticides, and other environmental issues. Its work is guided by major environmental laws like the Clean Air Act, Clean Water Act, and Safe Drinking Water Act, which target pollution control and public health protection.

In contrast, the Federal Communications Commission regulates communications networks and services, NASA concentrates on space exploration and aeronautics, and the Securities and Exchange Commission oversees financial markets and securities. The Environmental Protection Agency’s mission is specifically about environmental health and protection, which is why it’s the correct choice.
