Why are Internet sources with Web addresses ending in .org, .gov, or .edu generally a better source of medical information than sources with addresses ending in .com?

Addresses ending in .gov, .edu, or .org are often associated with government agencies, educational institutions, or organizations that provide medical information. A .com address alone does not show that a site is unreliable, but these sites are less likely to be affiliated with teaching hospitals or other established medical organizations. Therefore, B is the best choice; claims that all .com sites are untrustworthy or only promote money-making treatments are too broad.
