Answer: (C)

Cookies are primarily used to remember information about the user. They are small pieces of data that a website stores on a user's device while they are browsing. This stored information can include login details, preferences, and items in a shopping cart, which helps to streamline the user experience during subsequent visits to the website. For instance, if you log into an account, cookies can keep you logged in for future visits without the need to enter your credentials again.

This functionality allows websites to provide a more personalized experience, adapting the content and features based on the user's past interactions. Therefore, cookies play a critical role in enhancing user convenience and website efficiency by remembering user choices and behaviors.
