APEX B.An encyclopedia of Greek history with multiple authors that has been reviewed by experts

When writing a research paper, one must consider the use of credible sources – not all sources can be used for citation and reference. Blog posts are generally a no go, and even articles that aren’t published from reputable outlets are not advised to be included as a source.

Thus, from the options available, Peter would be safe to use (B) an encyclopedia of Greek history with multiple authors that has been reviewed by experts as a source.
