Diary and artifact.
Primary Sources come from the original time or event. A diary represents a first-hand account of something by the original person. An artifact does virtually the same thing, being from that time period. All the other choices are incorrect because they are often told in a way that changes the original story or event.

The other options are theories of the origins of man in the Americas, though there´s no consensus in the academic community.
