In copyright law, subsidiary rights refer to rights to publish a work in a form other than its original publication. Which of the following describes this concept?

• A. Public performance rights
• B. Derivative form rights
• C. Reproduction rights
• D. Moral rights

Answer: (B)

Subsidiary rights cover publishing or using a work in a form other than its original publication. The best description is derivative form rights, because this category includes creating new works based on the original—such as translations, film or TV adaptations, or other format changes like a novel becoming a graphic novel. This is different from reproduction rights, which are about making copies of the original text; public performance rights, which involve performing or broadcasting the work; and moral rights, which relate to the author's attribution and the work’s integrity. For example, licensing the right to turn a novel into a movie is a derivative form right.
