The request line, which includes the HTTP method (such as GET or POST) and the request URI, is required in a HTTP request. The request header, which contains additional information about the request (such as the user agent or the content type), is optional, but often included. The request body is also optional, but necessary for certain types of requests, such as when sending data in a POST request. Therefore, the best choice is E, which includes all three components: request line, request header, and request body.
