Which license requires giving credits to the author or licensor?

The Creative Commons Attribution License (CC-BY) requires users to provide credit to the author or licensor when utilizing the licensed material. This means that if someone wishes to share, remix, or adapt the work, they must acknowledge the original creator in a manner specified by the author. This is one of the foundational principles of this license, emphasizing the importance of giving appropriate credit to creatives while still allowing wider distribution and use of their work.

In contrast, the other options encompass different conditions that might not necessitate attribution in the same way. For instance, CC-SA (ShareAlike) mandates that any derivative works be licensed under the same terms but does not specifically emphasize the need to credit the original author in the way CC-BY does. CC-ND (No Derivatives) prohibits adaptations altogether, while CC-NC (NonCommercial) allows for use but restricts it to non-commercial scenarios. The specific requirement of providing credit is uniquely tied to the CC-BY license, highlighting its role in encouraging attribution as an integral part of content sharing.
