What percentage of a multimedia presentation can be lawfully used from copyrighted works?

The correct answer indicates that you can lawfully use up to 10% of a copyrighted work in a multimedia presentation under certain circumstances, particularly for educational or nonprofit purposes. This guideline aligns with fair use principles, permitting limited portions of a work to be used without permission, provided that the use is transformative and does not harm the market for the original work.

The rationale behind this specific percentage is that it balances the interests of copyright holders with the need for educational and creative use. Utilizing a small, defined fraction ensures that the core content of the work remains protected while allowing for limited educational application.

Other options, such as 5%, 20%, or 30%, do not conform to established fair use guidelines, which emphasize the importance of allowing a defined fraction to avoid infringing on the rights of copyright owners while promoting the advancement of knowledge and innovation.
