Imagine you're building a dashboard application where widgets can be added/removed by users. Which feature of Angular would be most suitable to achieve this dynamic behavior?

Angular Components are the most suitable for achieving dynamic behavior where widgets can be added or removed by users in a dashboard application. Components encapsulate the behavior and appearance of UI elements, making them reusable and easy to manage. While directives, services, and forms are essential in Angular, they are not as well-suited to handle the dynamic nature of widgets in this scenario.
