Final answer:
In incognito mode or private browsing, sites visited are not stored in browser history, and temporary files are set to be deleted after the session.
Step-by-step explanation:
When surfing the web anonymously, such as when using an incognito mode or private browsing feature, the websites you visit are not stored in the browser history, and the temporary files created during the session are supposed to be deleted after you close the incognito window. This means that the correct answer to the question is c) They are not stored in the browser history. However, this does not guarantee complete privacy, as your internet service provider, the websites themselves, and any network monitoring systems may still track your visits.
