Using NgModules in an Angular application provides several advantages, one of which is enabling lazy loading for performance optimization. Lazy loading is a technique that allows certain parts of an application to be loaded only when they are needed, rather than loading everything at once during the initial load. This is particularly beneficial for large applications, as it can significantly improve the loading time and overall performance.

When modules are structured properly, you can specify which modules should be loaded on demand. This approach not only enhances the speed at which the application becomes usable but also helps in reducing the browser's memory footprint, leading to a smoother user experience. By breaking an application into smaller, feature-specific modules, developers can optimize the loading of resources, making the application more efficient and responsive.

The other options do not align with the core functionalities of NgModules. For instance, while managing user sessions or enhancing animation effects may be important in an application, they do not specifically relate to the modular architecture facilitated by NgModules. Limiting functionality does not represent an advantage; instead, NgModules are designed to encapsulate and organize related functionalities, promoting maintainability and scalability.
