What is the full name and acronym of the federal agency that regulates pesticides?

The full name of the federal agency that regulates pesticides is the Environmental Protection Agency, commonly abbreviated as EPA. This agency is responsible for protecting human health and the environment by enforcing regulations and ensuring safe pesticide use in the United States. The EPA plays a crucial role in evaluating the safety and effectiveness of pesticides before they can be marketed.

The other options represent either incorrect names or acronyms of agencies that do not have the primary role of regulating pesticides. For instance, the Environmental Protection Administration is not the correct name; the proper designation includes the term "Agency." The Department of Pesticide Regulation (DPR) refers to a state-level agency in California dedicated to overseeing pesticide use within the state, rather than a federal agency. Similarly, the Pesticide Control Unit (PCU) is not a recognized federal agency associated with pesticide regulation. Therefore, the option that correctly identifies the federal agency overseeing pesticide regulation is the Environmental Protection Agency.
