The purpose of the @Component decorator is to define metadata for a component. In Angular, components are the building blocks of most applications, and the @Component decorator is a vital aspect of creating those components. It allows developers to provide specific information such as the selector, template, style, and other properties that dictate how the component behaves and is rendered in the application.

When you use the @Component decorator, you specify attributes like the component's HTML template, CSS styles, and the selector that is used to include that component within other parts of your application. This metadata essentially tells Angular how the component should be instantiated and displayed, making it a crucial part of component creation.

The other choices don't align with what the @Component decorator is intended for. For example, application routing is managed by the RouterModule and its configurations, not the @Component decorator. Similarly, handling HTTP requests is accomplished through services like HttpClient and is not part of component metadata. Lastly, creating services for dependency injection relates to the @Injectable decorator rather than to the @Component decorator.
