Concept:The domain name extension of a website indicates the type of organization that owns it.
Explanation:The website address is "www.google.com".
Its last part, ".com", stands for "commercial".
Commercial organizations run businesses to earn profit.
Google earns revenue mainly through advertising and other services.
It is a profit-making company, not a non-profit, research-only, or educational institution.
So ".com" clearly identifies Google as a commercial organization.
Answer:Google is a commercial organization.
Therefore, the correct option is A.
