The Klan Motel is one of twenty motels in town but the only one that refuses to rent rooms to non-whites. Congress holds that motels may not discriminate on the basis of race. The Klan Motel challenges the regulation as it applies to that motel. The owner will:
 a. win; so long as there are plenty of motels available, there is no significant effect on interstate commerce by such discrimination
  b. win; a motel is a place of private, not public, accommodations
  c. lose; all forms of racial discrimination are forbidden by the Commerce Clause
  d. lose if the state in which the motel is located has passed a similar law to apply to motels e. none of the other choices
