Final answer:
The 9th Amendment ensures that people's rights that are not specifically listed in the Constitution are retained by the people.
Step-by-step explanation:
The correct answer is OC. 9th Amendment.
The 9th Amendment to the United States Constitution ensures that people's rights that are not specifically listed in the Constitution are retained by the people. It states that the enumeration of certain rights in the Constitution shall not be construed to deny or disparage others retained by the people. This means that just because a right isn't explicitly mentioned in the Constitution, it doesn't mean that it doesn't exist and that the people still have those rights.
For example, the right to privacy is not explicitly mentioned in the Constitution, but it is protected by the 9th Amendment. This amendment acknowledges that individuals have rights that are not explicitly spelled out in the Constitution but are still protected.
