What type of license allows distribution of derivative works only under the same terms as the original?

• A. CC-BY
• B. CC-SA
• C. CC-ND
• D. CC-NC

Answer: (B)

The chosen answer, CC-SA, refers to the Creative Commons ShareAlike license. This license allows others to remix, tweak, and build upon a work, but it requires that any derivative works be licensed under the same or a compatible license. This means that if someone creates a new work based on the original, they must distribute it under the same terms—thereby maintaining the same freedoms for future users. This aspect of the CC-SA license is essential for fostering a collaborative environment where works can evolve while still giving credit to the original creator and ensuring that future contributions remain consistently open for others to use and adapt. It encourages a culture of sharing and creativity while maintaining a consistent licensing framework. In contrast, other options like CC-BY permits derivative works without requiring the same licensing terms, allowing for more freedom but potentially leading to a situation where original creator's work can be built upon under less permissive licenses. The CC-ND (No Derivatives) prohibits derivatives altogether, meaning the work can only be shared as is. CC-NC (Non-Commercial) limits usage to non-commercial purposes, allowing adaptations but not for profit, which diverges from the focus on licensing derivatives under the same terms.
