What type of Internet domain is assigned to URLs for business or commercial entities?

The domain type assigned to URLs for business or commercial entities is .com. This designation originally stood for "commercial" and has become the most recognized and widely used domain for businesses and online commerce. It serves as an indicator to users that the website is likely to be related to a commercial entity, making it a popular choice among businesses looking to establish their online presence.

While .edu is designated for educational institutions, and .org is typically reserved for non-profit organizations, .net was originally intended for network-related services but has evolved to be used more broadly. However, none of these extensions carry the same commercial connotation as .com. Thus, the .com domain is specifically aligned with businesses and commercial enterprises, highlighting why it is the correct choice in this context.
