Which url ending would indicate the LOWEST level of research reliability?

.com

A .gov url ending indicates a government website, which is likely to have the most accurate and updated statistics and information. A .edu ending means the page is from a recognized educational facility, and is therefore more likely to be monitored and accurate. A .org ending means the website was made by a well-recognized organization, lending them more credibility. Anyone can create a .com website, so it is always questionable whether the material there is accurate.
