What protects the right to reproduce and distribute creative written works?

The correct choice is copyright law, as it specifically exists to protect the rights of creators over their original works, including literary pieces. Copyright law grants authors and creators exclusive rights to reproduce, distribute, perform, display, or license their creative writings. This protection incentivizes creativity and ensures that creators can control how their works are used and compensated for, which is crucial in the publishing industry and beyond.

Other options do not relate to the protection of written works in the same way. For instance, security of court facilities pertains to the physical safety of courtroom spaces and does not influence intellectual property rights. Client confidentiality refers to the ethical duty of lawyers to protect their clients' private information, and joint retainers deal with agreements where two or more clients are represented by the same lawyer, neither of which serve to protect the reproduction and distribution of creative works. Thus, copyright law is the only choice directly associated with the protection of literary rights.
