The correct choice highlights a fundamental aspect of network services, particularly in relation to Avanti Denver's functionality as a server. Web services, specifically those using HTTP/HTTPS, are essential for serving web content and enabling communication between clients and servers over the internet. These protocols allow users to access web pages, applications, and online resources, making them integral to the server's operation.

HTTP (Hypertext Transfer Protocol) is the foundation of data communication on the web, while HTTPS (HTTP Secure) adds a layer of security through encryption, ensuring that data transmitted is safe from interception.
