Answer: (B)

The main purpose of browser cookies is to store user preferences and session information. Cookies are small pieces of data that websites store on a user's device when they visit the site. This allows the website to remember information about the user for their next visit, such as login credentials, preferences for display settings, items in a shopping cart, or other personalized information.

By storing this information, cookies enhance the overall user experience, enabling websites to provide a more tailored and efficient interaction. For instance, if you frequently visit a website and it remembers your preferred language or theme, that's due to cookies saving that information. This functionality is essential for websites that require users to log in or have a personalized interface.
