The ngFor directive is specifically designed to iterate over arrays and render lists in Angular templates. When using ngFor, you can create a template that repeats for each item in an array or collection. This functionality allows developers to dynamically generate UI elements based on the data model, making it highly efficient for creating lists or tables where the number of items can change based on user interaction or data updates.

For instance, if you have an array of items fetched from an API, you can use ngFor to generate an HTML list, displaying each item as a separate entry in the list. This provides a simplified way to manage and display repetitive content in your application without having to manually create each element in the HTML.

Given this context, other directives and methods referenced in the other choices serve different purposes entirely; forms are handled with form directives, navigating between views is managed by the Router, and styles are typically defined through Angular's style binding mechanisms or CSS files. Therefore, the focus of ngFor is distinctly on iterating over arrays and rendering those results seamlessly in the view.
