What is TRUE about a product's EPA registration?

A product's EPA registration signifies that it has been evaluated and approved by the Environmental Protection Agency for safety and efficacy when used according to the label instructions. Using the product contrary to the label is illegal because the label includes specific guidelines for safe handling, application, and disposal. These regulations are in place to ensure that consumers and the environment are protected from potential harm that could arise from misuse of the product.

While other options may refer to additional information regarding the product, they do not encapsulate the legal implications tied to the EPA registration. The label may indeed provide disposal instructions and safety hazard information, but the crux of the matter is that any deviation from the approved label use places the user or the environment at risk and is therefore defined by law as illegal.
