The correct answer is HTTP, which stands for Hypertext Transfer Protocol. It is the foundation of data communication on the World Wide Web and is specifically designed for transmitting hypertext documents, such as web pages, from a server to a client, typically a web browser. HTTP allows for the retrieval of linked resources across the internet, supporting the structure of the web by enabling features like hyperlinks and multimedia content. Its ability to facilitate communication between web clients and servers makes it essential for web browsing and online content delivery.

In contrast, the other protocols mentioned serve different purposes: SMTP (Simple Mail Transfer Protocol) is used for sending emails, FTP (File Transfer Protocol) is used for transferring files between computers, and POP3 (Post Office Protocol version 3) is used for retrieving emails from a mail server. Each protocol has its own specific functions in internet communications, but HTTP is the protocol that directly pertains to the transmission of web pages.
