The feature that enables Angular applications to function offline is service workers. A service worker is a script that the browser runs in the background, separate from the web page, and provides functionality such as caching resources, intercepting network requests, and enabling background synchronization. By implementing service workers, Angular applications can cache essential files and API responses on the client's device, allowing the app to load and function without a network connection. This capability enhances the user experience by providing faster load times and seamless access to the application even when the internet is unavailable.

In contrast, other options such as template-driven forms and reactive forms are related to handling user input and form validation within Angular applications. The HttpClient module is primarily responsible for making HTTP requests to retrieve or send data to a server. While these features are vital for building robust applications, they do not directly contribute to offline functionality.
