You find a blog post written by a student on a university website about photosynthesis. Assess the reliability of this source.

a. It may be reliable because other students verify the information in the blog.
b. It may be reliable because they cited other student blogs.
c. It may be reliable because they cited multiple peer-reviewed studies from scientific journals.
d. It may be reliable because the blog has been featured on a popular website.

c. It may be reliable because they cited multiple peer-reviewed studies from scientific journals.

Citing multiple peer-reviewed studies from scientific journals indicates that the information has been reviewed and approved by experts in the field. This increases the reliability and credibility of the source. The other options (a, b, and d) do not necessarily guarantee reliability as they rely on student verification, citing other student blogs, or popularity on a website, which do not ensure accuracy and factual information.
