The primary level of encapsulation provided by components in Angular is encapsulating both view and associated logic. In Angular, a component is a fundamental building block that combines the template (view) and the business logic into a cohesive unit. This encapsulation is essential for modularizing the application, promoting reusability, and ensuring that the component manages its own state and behavior independently from other components.

When a component is created, it defines not just how the user interface looks (the view) but also how it behaves (the logic behind the view). This means that any changes to the template or functionality of a component are self-contained, which greatly simplifies development and maintenance. Additionally, Angular’s data binding and lifecycle hooks further enhance this encapsulation, allowing for better interaction between the view and the component logic.

In contrast, options that suggest only supporting routing, encapsulating only business logic, or focusing solely on styling do not capture the full scope of what a component in Angular does. Components are designed to integrate the layout and functional logic cohesively, making them a powerful feature of the Angular framework.
