What risk do third-party cookies pose?

• A. They can limit data sharing with marketers.
• B. They prevent marketing data collection.
• C. They only work on one site.
• D. They can enable sharing and sale of your data to unknown marketers, reducing your control.

Answer: (D)

Third-party cookies are saved by sites other than the one you’re visiting, and they let advertisers and data brokers follow your activity across multiple sites. This cross-site tracking builds a broad picture of your interests and behavior, which can then be shared or sold to unknown marketers. Because you didn’t authorize all these actors or specify who can see your data, you end up with much less control over how it’s used. That loss of control and potential misuse is the primary risk. The other options don’t reflect how third-party cookies work: they don’t limit data sharing, they don’t prevent marketing data collection, and they aren’t confined to a single site.
