In response to massive layoffs of employees of automobile assembly plants located in the state of Ames, the legislature of that state enacted a statute which prohibits the parking of automobiles manufactured outside of the United States in any parking lot or parking structure that is owned or operated by the state or any of its instrumentalities. This statute does not apply to parking on public streets. Which of the following is the strongest argument with which to challenge the constitutionality of this statute? 
The statute imposes an undue burden on foreign commerce. The statute denies the owners of foreignmade automobiles the equal protection of the laws. The statute deprives the owners of foreign-made automobiles of liberty or property without due process of law. The statute is inconsistent with the privileges and immunities clause of the Fourteenth Amendment.
