Which of the following examples is eligible for copyright protection?

Sculptures are eligible for copyright protection because they are classified as original works of authorship fixed in a tangible medium of expression. Copyright law safeguards the expression of ideas rather than the ideas themselves, and sculptures are a form of artistic expression that can be uniquely created by an artist. As a result, the creator of a sculpture holds exclusive rights to reproduce, distribute, and display their work.

In contrast, newspaper articles can be subject to varying copyright protections based on the content and the writer's originality, although they are typically protected. Scientific formulas, however, are generally not eligible for copyright protection because they are considered factual information or ideas, rather than expressions of creativity. Public domain works are not eligible for copyright protection, as they are works whose copyright has expired or were never eligible for copyright in the first place, meaning they can be freely used by anyone.
