A URL is composed of which main parts?

• A. Scheme and host only.
• B. Path and fragment only.
• C. Scheme, domain, path, and optionally port, query, and fragment.
• D. Protocol and encryption.

Answer: (C)

A URL is built from several pieces that tell you how to reach a resource and what to request. The main parts are the scheme (or protocol) that defines how to fetch the resource, the domain or host where the resource lives, and the path that locates the specific resource on that host. In addition, a URL can include a port if you’re using a non-default entry point, and it may have a query string after a question mark to pass parameters and a fragment after a hash to refer to a section within the resource.

So a typical URL like https://example.com:8080/path/to/resource?search=term#section2 shows all of these: the scheme (https), the host (example.com), an explicit port (8080), the path (/path/to/resource), the query (?search=term), and the fragment (#section2). The essential parts are scheme, domain/host, and path, with port, query, and fragment being optional.

The other options don’t capture all the main pieces. One misses the path entirely, another leaves out the scheme and host, and a fourth treats encryption as its own URL part, which isn’t how URLs are structured.
