Under which act do copyright holders have the right to reproduce and create derivative works?

The correct choice is the Copyright Act of 1976. This act significantly expanded the rights of copyright holders and established the legal framework for copyright in the United States. Under this act, copyright holders are granted exclusive rights to reproduce their works and to create derivative works based on their original creations. This means they can control how their works are used, adapted, or altered, thereby ensuring that they receive recognition and financial benefits from their intellectual property.

The Copyright Act of 1976 established that copyright protection covers both published and unpublished works and provides a lengthy term of protection, ensuring that creators have a substantial period during which they can monetize their work.

Other acts, such as the Copyright Act of 1951, primarily established foundational copyright principles but did not offer the exhaustive rights introduced in 1976. The Digital Millennium Copyright Act focuses on issues surrounding digital infringement and online content, while the Intellectual Property Act is a broader term that does not specifically pertain to copyright law in the same way as the 1976 act.
