URL stands for :

A Uniform Resource Locator (URL), popularly referred to as a "web address", is a structured string of characters that references a resource globally across the computer network and specifies the mechanism (protocol) to retrieve it.

As illustrated in standard networking, a typical URL is broken down into distinct functional parts:

1. Protocol: Specifies how data is transferred (e.g., http:// or secure https://).

2. Domain Name (Host): The unique name that identifies the web server hosting the asset (e.g., [www.example.com](https://www.example.com)).

3. Path: The specific directory routing on the server leading to the resource (e.g., /images/logo.png).

Because it provides a uniform format to locate any unique web resource, Option C is the only correct expansion.
