I know how to pas arguments while calling a URL, but my doubt is in option=com_content&view=article. Please clarify my doubt. Please give more information about this.

Those are variables which will appear in the $_GET array (and often the $_REQUEST array -- $_REQUEST usually contains everything that $_GET does, but there are some exceptions). They are normally (but not always) put there by a form with "get" as the method attribute in HTML or they are put there in some anchor href attribute directly.

If you have option=com_content&view=article, then $_GET['option'] will equal "com_content" and $_GET['view'] will equal "article"

If you're interested in learning more, I recommend the tizag tutorial, which goes into a little more depth than I have.
