A state legislature passes a statute prohibiting businesses from supporting any political candidate. If some business owners challenge the constitutionality of the law in court, will the law be upheld?
a. No, because the business owners' privileges and immunities have been violated.
b. Yes, because the law only prohibits political speech by businesses, not by individual citizens.
c. Yes, because political speech is restricted if "constitutionally permissible."
d. No, because the law is an unconstitutional restriction on free speech.
