A city adopts an ordinance requiring the operators of massage parlors to receive licenses from the city. In the absence of more complete information, what would you say about the chances of successfully challenging the ordinance on constitutional grounds?

(A) Weak - the Court probably will uphold after applying rational basis test. (B) Strong - the Court will probably strike down on "right of privacy" grounds. (C) Strong - the Court will probably strike down on equal protection grounds unless the city also licenses most other businesses. (D)Fairly strong - the court will probably apply middle-tier scrutiny since sex is involved.
