3. Congress passed a law forbidding the US mails to be used from the distribution of unsolicited advertising for contraceptives. This led to litigation in the federal courts regarding the constitutionality of the statute.
The best argument against the constitutionality of the statute is that:
A. The statute offends certain rights that give rise to a constitutional right of privacy.
B. The statute constitutes a taking without due process of law.
C. The statute improperly infringes on the commercial speech protection of the First Amendment.
D. The statute unduly burdens interstate commerce.
