b. judicial activism, because it was based on a constitutional right to privacy that is not found in the actual words of the Constitution.

Explanation:

Judicial activism is a concept developed in 1947 by an American historian called Arthur M. Schlesinger, Jr. it simply talks about a description of a judicial decision made in a law court, in which the judge is more concerned with deciding constitutional issues and invalidating executive or legislative actions.  

A clear example of this is the Roe v. Wade case where the supreme court of the United States of America rightly established on January 22, 1973, a woman’s legal right to have an abortion.
