Explanation:

• Plug - ins: These are software components that add specific features to a larger software application. For example, a PDF - viewing plug - in for a web browser. They are not used for remembering users and preferences.
• Extensions: Similar to plug - ins in some ways, browser extensions add functionality like ad - blocking or password management. But they are not the data files for remembering user info.
• Bookmarks: These are saved links to web pages. They help users quickly access their favorite or frequently visited sites, not for remembering user preferences in general.
• Cookies: These are small data files. Websites use them to store user - specific information such as login status, language preferences, shopping cart contents (in an e - commerce context). So, they fit the description of being used by websites to remember users and their preferences.
