 Answer: The statement that is not true about cookies  is: c. Cookies cannot be easily detected or deleted.

Cookies are small text files that are stored on a user's computer by a website. They can be used for a variety of purposes, such as supporting the user experience on websites or tracking user behavior across multiple websites. However, cookies can be easily detected and deleted by the user.

Most web browsers provide users with the ability to view and manage cookies, either through built-in settings or via third-party extensions. Users can typically view a list of the cookies stored on their computer, as well as delete individual cookies or clear all cookies at once.

While cookies may sometimes be installed at the user's request (e.g. to remember login credentials), they can also be installed automatically by websites without the user's explicit consent. It is also true that cookies can be combined with other website data to develop detailed profiles of customers, and that they are stored on the user's computer.

This statement is true. Cookies can be used to track user behavior across multiple websites, and the data collected can be combined with other website data to develop detailed profiles of customers. This is sometimes done for advertising or marketing purposes, although it can also raise privacy concerns.

In conclusion, cookies are small text files that are used by websites for a variety of purposes, including supporting the user experience, tracking user behavior, and developing detailed customer profiles. While cookies can be useful, they can also pose privacy and security risks, as they can potentially be used to track user behavior across multiple websites and may contain sensitive information. It is important for users to be aware of cookies and their potential risks, and to take steps to manage cookies and protect their privacy while browsing the web. This may include periodically deleting cookies or configuring web browsers to block or limit their use.
