A Right to Privacy, While Recognized Over Time by Federal

A right to privacy, while recognized over time by federal judges, is not explicitly mentioned in the Constitution.It can be said that such a right is protected under the Constitution, all the same, because:

A) the Supreme Court, which has the final say in interpreting the document, has said it is.
B) Congress decided that it was necessary and proper to give Americans privacy protections under federal law.
C) the Ninth Amendment asserts that a failure to mention a right does not mean it is not possessed by the people.
D) more democracy in America brought about a greater judicial concern with individual liberty, despite the fact that judges are appointed, and serve lifetime appointments.
