The correct answer is D .org
Step-by-step explanation:
On the internet, a domain refers to a specific name, label or element that is used to identify the type of entity that controls a website. These are part of the URL of the webpage or the address/link used to find a webpage. In the case of organizations including profit and non-profit ones, the domain that is internationally used in .org as this is an abbreviation for the word "organization"; for example, the UNICEF (United Nations International Children's Emergy Funds) webpage contains this domain as this entity is an organization. Thus, the domain that is used for a profit organization is .org.
