After several well-publicized deaths caused by fires in products made from highly flammable fabrics, the state of Orange enacted a statute prohibiting "the manufacture or assembly of any product in this state which contains any fabric that has not been tested and approved for flame retardancy by the Zetest Testing Company." The Zetest Testing Company is a privately owned and operated business located in Orange. For many years, Fabric Mill, located in the state of Orange, has had its fabric tested for flame retardancy by the Alpha Testing Company, located in the state of Green. Alpha Testing Company is a reliable organization that uses a process for testing and approving fabrics for flame retardancy identical in all respects to that used by the Zetest Testing Company. Because Fabric Mill wishes to continue to have its fabric tested solely by Alpha Testing Company, Fabric Mill files an action in Orange state court challenging the constitutionality of the Orange statute as applied to its circumstances. In this suit, the court should hold the statute to be
constitutional, because it is reasonably related to the protection of the reputation of the fabric industry located in the state of Orange.  constitutional, because it is a legitimate means of protecting the safety of the public.  unconstitutional, because it denies to Fabric Mill the equal protection of the laws.  unconstitutional, because it imposes an unreasonable burden on interstate commerce
