What real issue is associated with third-party cookies?

• A. Your information and your interests are being shared with persons and companies you don't know, and that information can then be sold to other marketing organizations so that data about you is no longer in your control.
• B. They encrypt all data on the device.
• C. They automatically delete cookies after each session.
• D. They restrict data collection to the user's own site.

Answer: (A)

Privacy and data tracking are the central concerns with third-party cookies: they let entities beyond the site you’re visiting collect information about your browsing and share it across different sites. This creates a broader profile of your interests and behaviors, which can be sold or used by marketers and data brokers you don’t know or interact with directly, often without your explicit consent. That loss of control over how your data is used is what makes third-party cookies problematic.

The other statements don’t capture what third-party cookies do: they don’t inherently encrypt data on your device; they don’t automatically delete cookies after each session; and they don’t limit data collection to the site you’re visiting—quite the opposite, they enable data collection across multiple sites.
