The King City zoning ordinance contains provisions restricting places of "adult entertainment" to two specified city blocks within the commercial center of the city. These provisions of the ordinance define "adult entertainment" as "live or filmed nudity or sexual activity, real or simulated, of an indecent nature." Sam proposes to operate an adult entertainment establishment outside the twoblock area zoned for such establishments but within the commercial center of King City. When his application for permission to do so is rejected solely because it is inconsistent with provisions of the zoning ordinance, he sues the appropriate officials of King City, seeking to enjoin them from enforcing the adult entertainment provisions of the ordinance against him. He asserts that these provisions of the ordinance violate the First Amendment as made applicable to King City by the Fourteenth Amendment. In this case, the court hearing Sam's request for an injunction would probably hold that the adult entertainment provisions of the King City zoning ordinance are 
constitutional, because they do not prohibit adult entertainment everywhere in King City, and the city has a substantial interest in keeping the major part of its commercial center free of uses it considers harmful to that area.  constitutional, because adult entertainment of the kind described in these provisions of the King City ordinance is not protected by the free speech guarantee of the First and Fourteenth Amendments.  unconstitutional, because they prohibit in the commercial area of the city adult entertainment that is not "obscene" within the meaning of the First and Fourteenth Amendments.  unconstitutional, because zoning ordinances that restrict freedom of speech may be justified only by a substantial interest in preserving the quality of a community's residential neighborhoods.
