In an Effort to Protect Its Dairy Industry,a Provincial Government

In an effort to protect its dairy industry,a provincial government passed a law that prohibits the importation or manufacture of soy milk.If a soy milk company challenges that statute on constitutional grounds,what would a court likely say?

A) Because property rights are protected by the Charter,the statute is constitutionally invalid.
B) Inter-provincial trade is an issue that provinces are entitled to decide for themselves.
C) The federal government has jurisdiction over international trade but not over inter-provincial trade.
D) The statute is entirely ultra vires because federal jurisdiction over international and inter-provincial trade extends to every issue that is related to trade,including the manufacture or production of soy milk.
E) The statute is at least partially intra vires because provinces have the authority to regulate the production or manufacture of things like soy milk within the province but the law may be constitutionally ultra vires as interfering with the federal jurisdiction over inter-provincial trade,or mobility rights pursuant to the Charter.
