What happens to cookies after you close your web browser?

When you close your web browser, cookies that are classified as session cookies are typically deleted, while persistent cookies remain until they expire or are explicitly cleared by the user. Persistent cookies have a set expiration date and are stored on the user's device even after the browser is closed. This design allows websites to remember the user's preferences and login details for future visits. Session cookies, on the other hand, are temporary and are removed once the browser is closed.

In this context, the correct answer reflects that cookies can persist after the browser is closed until the user decides to delete them, thus explaining why the answer indicates they remain until explicitly cleared. This understanding is crucial for users who want to manage their browsing history and privacy effectively.
