The correct answer is B. Turn off notifications in the browser, because the described behavior matches browser notification abuse, not traditional pop-ups. Modern browsers allow websites to request permission to send notifications. If a user previously allowed notifications from a retail site, the site can continue sending onscreen alerts even when pop-up blockers are enabled.
According to the Quentin Docter – CompTIA A+ Complete Study Guide, browser notification permissions are separate from pop-up blocking settings. Pop-up blockers prevent new browser windows or tabs from opening, but they do not block push notifications that were previously approved by the user. These notifications can persist long after visiting a site.
The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that one of the first troubleshooting steps for repeated browser messages is to review and disable site notification permissions. This directly targets the root cause without affecting browser configuration or user data.
The Mike Meyers / Mark Soper Lab Manual reinforces that resetting or reinstalling the browser is an excessive step unless configuration corruption is suspected. Clearing cache removes stored files but does not revoke notification permissions.
Because the messages originate from previously allowed browser notifications, the most appropriate and targeted fix is to disable notifications in the browser, making B the correct answer.
