Structural directives like *ngFor are specifically designed to manipulate the structure of the DOM by adding or removing elements based on conditions or collections of data. In the case of *ngFor, it is used to iterate over a collection, such as an array, and create a template instance for each item in that collection. This results in the seamless generation of a list in the application's view, with each instance reflecting the data associated with each item.

When using *ngFor, you can easily create dynamic lists that adjust based on the changes in the underlying data array. This is essential in scenarios where the data is dynamic, and you need the view to update accordingly. For example, displaying a list of products, users, or any other collection becomes straightforward, allowing developers to focus on business logic without worrying about manual DOM manipulation.

The other options, while relevant to Angular development, serve different purposes. Binding data to form elements relates to two-way data binding, responding to user events pertains to event binding capabilities in Angular, and styling the application layout usually involves the use of styles and CSS rather than structural directives. Each of these plays a distinct role within Angular applications, showcasing the framework's versatility.
