Which one of the following statements is FALSE ?

The correct answer is Option B because HTTP (Hypertext Transfer Protocol) defines the rules for transferring data between a client and a server, not the structure of web pages themselves. The structure of web pages is actually defined by HTML (Hypertext Markup Language), which uses tags to organize content like text, images, and links. Option A is true because HTTP relies on TCP to ensure reliable data transmission over the internet. Option C is also correct as URLs can contain query parameters (e.g., id=123) that allow information to be passed and stored within the request. Option D is valid since HTTP requests can verify if a resource exists (e.g., checking for a 404 error) to test link validity. Therefore, Option B is the only false statement as it confuses HTTP with HTML.
