Final answer:
Option b, which states that Creative Commons is a type of copyright license allowing other creators to use works as part of new projects, is the correct definition. It provides a way for copyright holders to grant certain rights to the public while retaining others. These licenses facilitate the sharing and building of creative works, under specified terms.
Step-by-step explanation:
The correct description for Creative Commons is that it is a type of copyright license that allows creators to expand upon or use other creators' works in their projects, often with certain restrictions based on the license chosen by the copyright holder. This enables the copyright holder to grant some of their rights to the public while retaining others. So, b. Creative Commons is a type of copyright license that allows other creators to use works as part of new projects is the correct option.
According to the U.S. Copyright Office, copyright is a legal form of protection for 'original works of authorship' and includes a range of creative pieces such as literary, dramatic, musical, and pictorial works, among others. Once a work is created, copyright protection is automatically in effect for the life of the author plus 70 years. However, through a Creative Commons license, authors can voluntarily share their work under specified conditions that allow for reuse and distribution.
