What does the acronym "EPA" stand for?

The acronym "EPA" stands for the Environmental Protection Agency. This U.S. federal agency is responsible for regulating and enforcing national standards in various environmental areas, including air quality, water quality, and pesticide control. The EPA oversees the registration and approval of pesticides, ensuring they are safe for use and do not pose undue risks to human health or the environment.

The other options do not accurately represent the EPA's function or name. For instance, "Environmental Processing Association" does not correspond to any recognized agency or organization involved in environmental protection. "Effective Pesticide Administration" suggests a focus on pesticide management but does not reflect the broad mission of the actual agency. Lastly, "Endangered Protection Act" implies a specific legislation aspect rather than the overarching agency aimed at protecting the environment as a whole. Thus, the correct choice highlights the significance of the EPA in environmental governance.
