Prosecutor Reeves charges that your $10,000 contribution to Lucinda Snopes is illegal under a Georgia law that prohibits corporations from donating any money to political campaigns. You argue that this law infringes on your constitutional right to freedom of speech. You are:
a. correct, state laws may not infringe upon constitutionally guaranteed rights such as freedom of speech
b. correct, the state restriction is too far reaching
c. incorrect, because your speech impedes interstate commerce and so cannot be considered "free speech"
d. incorrect, because states may prohibit the use of corporate money for supporting political candidates
e. correct, under the ruling of Southern Pacific v. Arizona
