Which of the following, if true, can best weaken the above argument? ['There are many unregistered companies registered in the country.', "Some businesses don't know how to register a web domain name.", 'Companies that do not register domain names do not necessarily have sound, keen "network awareness".', 'Registering a domain name is currently too cumbersome and the fees are high, many companies consider it uneconomical.']
