What happens to products in the cart if a user is not logged in?

When a user is not logged in to their account and adds products to their shopping cart, those products are saved for that session only. This means that while the user continues to browse the site, they can still view and modify their cart as long as they do not leave the site or close their browser. Once the session ends—either by leaving the site or closing the browser—the items in the cart are typically cleared, and the user will not have access to them in future visits unless they log in to an account where such functionality is enabled.

For users who are not logged in, the cart contents are not tied to any persistent user account, which makes them temporary. Therefore, if the session is lost, the items will not persist for any time beyond that browsing instance. Items stored in the cart for logged-in users, however, will remain even after they log out, allowing them to retrieve their selections on future visits.

This temporary nature highlights the importance of user login and account creation for retaining cart contents and enhances the shopping experience by allowing users to come back to their cart and complete their purchases without losing their selections. In conclusion, option A accurately reflects the behavior of the shopping cart for users who are not logged in.
