The correct answer is: The written work is not covered by copyright law and is fair game for others to use.
In copyright law, a written work must be original and fixed in a tangible medium of expression to be protected. If a work is not original (meaning it does not contain a sufficient degree of creativity and is not the author's own creation) and is not in a fixed form (meaning it is not recorded in some physical way), it does not qualify for copyright protection. Therefore, it can be used by others without permission.
