What is the three-letter abbreviation for the U.S. government agency that acts as a watchdog for environmental matters?

• A. EPA
• B. NASA
• C. CIA
• D. FDA

Answer: (A)

The Environmental Protection Agency, abbreviated EPA, is the federal agency charged with protecting the environment and enforcing environmental laws. It sets and enforces standards for air and water quality, regulates pollutants, and ensures compliance to keep ecosystems and public health safe. That watchdog role is exactly what the EPA does at the national level.

NASA focuses on space exploration, CIA handles intelligence, and FDA oversees the safety of foods and medicines. None of these are the primary agency responsible for environmental oversight, so EPA is the correct three-letter abbreviation.
