In the decision concerning Griswold v. Connecticut (1965), the Supreme Court relied on which of the following?
a) principles relating to procedural due process
b) the right to privacy as implied in the 1, 3,4,5,9, and 14th Amendments
c) the moral suasion of the general public
d) specific references to 'right to life' as implied in the 1,4,5,9, and 14th Amendments
e) the right of privacy protected by the 21st Amendment
The correct answer here is B.
Griswold v. Connecticut was the first major Supreme Court decision to propound a Constitutional right to privacy. Of course, such a right is nowhere to be found in the explicit language of the Bill of Rights. In Griswold the Court found this right in the "penumbras" of the amendments that you mention. The Court ruled that the amendments that you mention all imply that there is a right to privacy. The reasoning was that, for example, the idea that you have a 4th Amendment right against searches and seizures implies that you have a more general right to privacy.
For this reason, B is the correct answer.
