C. URL

Explanation

Web pages are uniquely identified by using Uniform Resource Locators (URLs). A URL is a specific web address that points to a particular web page or resource on the internet. It consists of several components, including the protocol (e.g., http, https), domain name (e.g., www.example.com), and optional path and parameters, which together uniquely identify the location of the web page or resource.
