What are you allowed to do with content on YouTube that has a Creative Commons licence?

Creative Commons licenses allow creators to share their work while retaining copyright, and they specify how others can use that work. "Reuse per terms of the license" is correct because the specific terms (e.g., attribution, non-commercial, share-alike) dictate what is permissible. Some Creative Commons licenses allow commercial use, making "Only use for non-commercial works" incorrect as a blanket statement. "Claim as original work" is incorrect because Creative Commons licenses require attribution to the original creator. "Use without attribution" is incorrect because all standard Creative Commons licenses require attribution (CC BY).
