What type of works does copyright protect?

Copyright protection extends to an "original literary, dramatic, musical, or artistic work," which encompasses a wide range of creative expressions. This definition is essential because it highlights that copyright does not only cover one type of work but rather includes various forms of creativity, provided they are original and fixed in a tangible medium.

Literary works encompass written documents, novels, poems, and scripts; dramatic works cover plays and choreographed performances; musical works include compositions and recordings; and artistic works relate to paintings, sculptures, and similar creations. This broad scope of protection ensures that creators have rights over their respective works, allowing them to control their use and distribution.

The other options are too narrow or inaccurate. For instance, limiting protection solely to musical works or artistic works fails to recognize the full range of copyright-protected material. Additionally, the option stating "all published materials" is overly broad and does not reflect the requirement for originality and fixation in copyright law. Thus, option C accurately captures the comprehensive nature of copyright protection.
