Cookies and data collection relate to media exposure by which of the following means?

• A. They slow down websites.
• B. Tracking technologies collect user data to personalize content and ads, impacting privacy and user agency.
• C. They delete browser history automatically.
• D. They guarantee user anonymity online.

Answer: (B)

Cookies and data collection work by gathering information about what you do online so your media experience can be tailored. The best answer captures the idea that tracking technologies collect user data to personalize content and ads, which directly affects privacy and user agency. This shaping of what you see—through personalized recommendations, ads, and feeds—determines your media exposure and can influence what information you encounter and consider. It isn’t primarily about slowing websites; while performance can vary, the defining point is data collection for personalization. They don’t automatically delete your history, and they do not guarantee anonymity online.
