Final answer:
A .edu site is more likely to be credible because it belongs to an educational institution, which requires verification for the domain. .com sites, on the other hand, can be owned by anyone, making their credibility variable.
Step-by-step explanation:
The student is asking about the credibility of two websites, one with a .edu domain and the other with a .com domain. In this context, the edu site is more likely to be credible because its domain indicates that it belongs to a university or other educational institution. .edu domains are restricted and require verification, making them more reliable for educational content. On the other hand, .com sites can be owned by anyone, and their credibility might vary.
