Which statement is true regarding the capability of cookies?

Cookies play a crucial role in web browsing by temporarily storing small pieces of data on a user's device. One of their primary functions is to track user behavior. When a user interacts with websites, cookies record information such as pages visited, time spent on the site, and preferences. This data helps website owners understand how users engage with their content, allowing them to enhance the user experience through personalization and targeted advertising.

By using cookies, websites can remember users' login information, shopping cart items, and other details to streamline interactions. Tracking user behavior through cookies is fundamental for analytics purposes, which can improve website design and functionality based on actual usage patterns. Understanding how users navigate a site can lead to better business decisions and more relevant content for visitors.

The other statements do not accurately represent the capabilities and limitations of cookies. Cookies do not hold executable code, cannot guarantee protection from threats, and cannot operate without user consent in most modern web applications due to privacy regulations.
