Answer: (ii) HTTP describes the structure of web pages

Why: HTTP is only a request/response transfer protocol; the structure (markup) of web pages is described by HTML, not by HTTP. The other statements are true — HTTP runs over TCP (port 80/443), it can carry data inside the URL/query string (iii), and status codes such as 404 Not Found can be used to test whether a hypertext link is valid (iv).
