In the case of McDonald v. Chicago the US Supreme Court selectively incorporated which part of the Bill of Rights?

In McDonald v. Chicago, the U.S. Supreme Court selectively incorporated the Second Amendment, which protects the right to keep and bear arms. The Court ruled that this right is applicable to the states through the Fourteenth Amendment's Due Process Clause. This decision effectively extended the Second Amendment's protections against state and local government infringement, reinforcing the individual right to possess firearms for self-defense.
