The Environmental Protection Agency passed regulations that controlled the limits of greenhouse gas emissions allowable by power plants. One plant felt that the limits were unnecessary and disagreed with the concept of global warming. Assuming that other plants decided to join together to fight the restrictions on their emissions, what must the EPA do?

a. The EPA, as an administrative agency, must uphold the regulations agreed upon by a consensus of businesses with expertise in the field.

b. The EPA, as an administrative agency, must promote the health and safety of workers.

c. The EPA, as an administrative agency, must modify their regulations to meet the new consensus by the power plants.

d. The EPA, as an administrative agency, must promote public welfare through the protection of the environment, including creating and defending regulations to limit potential environmental harm.
