What are the main components of a URL?

• A. Scheme, host, path, query, and fragment
• B. IP address, port, path
• C. Protocol and domain
• D. Host and resource

Answer: (C)

The main idea being tested is the two essential parts that identify where a resource lives and how to reach it: the protocol and the domain. The protocol (scheme) tells the browser how to talk to the server—examples include http and https—while the domain (host) specifies which server to contact. Together, they establish the address and the method for retrieval. Other pieces like the path, query, and fragment add details about the specific resource or how to interact with it, but they aren’t needed to locate the resource in the first place.

The other options either list more parts of a URL than the core two or omit the protocol, which is necessary to know how to access the host.
