Which of the following best describes what happens during the closing phase of a web page lifecycle?

During the closing phase of a web page lifecycle, resources associated with the page are typically cleaned up and released. This includes processes such as deallocating memory, removing event listeners, and shutting down any ongoing connections that the page may have established during its lifecycle. By cleaning and releasing these resources, the system helps prevent memory leaks and ensures that the application runs efficiently.

The other options, while relevant to various aspects of web development, do not accurately describe what specifically occurs during the closing phase. For instance, final rendering relates to how the page is displayed to the user and occurs prior to the closing phase. Sending data to a database can happen at various points during the page lifecycle but is not specifically tied to the closing phase. Encrypting user data is a security measure that may also happen during data transmission or storage, rather than as part of the web page's closing activities.
