A right is unenumerated if it is C. assumed to be a fundamental right.

Explanation:

In the United States legal system, the Ninth Amendment as well as the Fourteenth Amendment to the U.S. Constitution protect against the infringement of unenumerated rights, that are those fundamental legal rights that are not expressly coded but are indeed inferred from other existing laws like the Constitution and, consequently, recognized by the U.S. legal system.

The Supreme Court of the United States found among the unenumerated rights the right to travel, the right to keep personal matters private and the right to make decisions about one's body or health.
