In a web server, ten WebPages are stored with the URLs of the form http://www.yourname.com/$var$.html; where, $var$ is a different number from 1 to 10 for each Webpage. Suppose, the client stores the Webpage with $var = 1$ (say W1) in local machine, edits and then tests. Rest of the WebPages remains on the web server. W1 contains several relative URLs of the form "$var$.html" referring to the other WebPages. Which one of the following statements needs to be added in W1, so that all the relative URLs in W1 refer to the appropriate WebPages on the web server?

When an HTML document contains relative URLs, the browser resolves them against a base URL.

• By default, the base URL is the location of the document itself. If document W1 is stored locally, relative links like "2.html" will be resolved relative to the local file system path (e.g., file:///.../2.html), which fails to locate the pages on the remote web server.

• The HTML <base> tag specifies the base URL/target for all relative URLs in a document.

• By adding <base href="http://www.yourname.com/"> in the <head> section of W1, all relative links inside W1 will automatically resolve against http://www.yourname.com/, directing requests to the proper web server.

Thus, option (B) is the correct choice.
