When conducting internet research, which of the following domain extensions will provide the least credible resources?

The domain extension .com is widely used and stands for "commercial." Websites with this extension are often created for business and profit-driven purposes, which can sometimes lead to a lack of reliability or a potential bias in the information they provide. While there are certainly reputable .com websites, the proliferation of commercial sites also means that many may prioritize marketing over factual accuracy.

In contrast, the .org domain is typically used by non-profit organizations, which can provide credible information, especially in fields like education and advocacy. The .edu extension is restricted to educational institutions, lending a high level of credibility to the information from these sources. Similarly, the .gov extension is restricted to government entities and, as a result, generally offers reliable and factual content.

Since .com websites are not bound by the same standards of credibility as .edu, .gov, and even .org sites, it is reasonable to conclude that they are often the least credible resources when conducting internet research.
