What is the purpose of the ninth amendment

To list out citizen's rights
To give states rights
To keep government from only giving citizens rights listed
To keep states from only giving citizens rights listed

The purpose of the Ninth Amendment to the United States Constitution is to ensure that the enumeration of certain rights in the Constitution will not be construed to deny or disparage other rights retained by the people. In other words, it establishes that the people have additional rights beyond those specifically listed in the Constitution, and that these rights should be protected. It does not give states or the government any particular rights but rather clarifies the limits of their powers.
