Which statement correctly differentiates session cookies from persistent first-party cookies?

• A. Session cookies are normally deleted when you exit the site; persistent first-party cookies are not erased when you leave.
• B. Session cookies persist across browser restarts; persistent first-party cookies are erased after closing the browser.
• C. Session cookies are stored for the current session only and are normally deleted when you exit; persistent first-party cookies are not erased when you leave and can remember you.
• D. Both types are always deleted after a set time.

Answer: (C)

The key idea is persistence: session cookies are temporary and disappear when you end the browsing session, while persistent cookies stay on your device across sessions because they have an expiration date. A cookie labeled as first-party comes from the site you’re visiting, and a persistent first-party cookie continues to exist after you leave the site, allowing it to remember you on future visits. So the statement is best because it accurately describes that session cookies are meant for the current session and are normally deleted when you exit, whereas persistent first-party cookies remain after you leave and can remember preferences or login state. The other options either misstate how and when session cookies are deleted or imply complete, permanent deletion of all cookies after a set time, which isn’t how cookies are defined.
