Question: Which of the following is true of Content ID?
- Content ID is only available to channels with >1 million subscribers.
- Content ID scans all uploads and removes portions that infringe copyright.
- Content ID enables rights holders to block, track, or monetize uploads that use copyrighted content.
- Content ID allows viewers to flag harmful or dangerous content.
Explanation
Content ID is YouTube’s automated rights management system for identifying copyrighted material in uploaded videos. When a match is found, the rights holder’s policy determines what happens to the claimed video. Available policy actions include blocking availability, tracking viewership data, or enabling monetization. This lets rights holders manage use of their content at scale through Studio Content Manager.
Why the other options are incorrect
Subscriber threshold is incorrect because Content ID eligibility is based on rights management needs, not a fixed subscriber count.
Automatic removal is incorrect because Content ID applies policies rather than simply deleting matched portions of videos.
Viewer flagging is incorrect because harmful content reporting is handled through YouTube community reporting tools, not Content ID.
