The correct answer is D. All of the above. Music, books, and website content are all covered by copyright. Copyright protection grants exclusive rights to the creators of these works, giving them control over how they are used and distributed. If you are ever unsure about what is covered by copyright, it's always a good idea to consult the specific laws in your country or seek legal advice. For instance, in the United States, copyright protection is automatically granted to creative works upon their creation, but it is always beneficial for creators to register their works with the U.S. Copyright Office to strengthen their legal rights and access additional protections.
