Explanation:

Out of all mentioned above, the best for developing the progressive app is certainly the Ionic. This is because it is an open-source, hybrid mobile app, cross-platform, and comes with the services and tools that are required for developing the app using web technologies like HTML5, Sass, and CSS. And Ionic happens to be the cheapest of all the framework mentioned above. Hence, it is the correct option.
