C.) Kennewick Man has more in common with Native Americans than with any other group

Explanation:

The term "Kennewick Man" started when a group of students came across a human skull in Columbia River, which was near Kennewick. The skull was first thought of as a victim of murder but later on, they found out that it was a very old skull.

Several scientists argued regarding the origin of the "Kennewick Man." The first speculation was that he was of European origin. However, analysis of his DNA proved that he wasn't European. The possibility that he was related to the Native Americans then followed. They analyzed the DNA by comparing it with different nationalities around the world. The result turned out that Kennewick Man has more in common with the Native Americans. The only problem was the shape of the skull.

Scientists have studied it more extensively and found out that the "Colville DNA" (a Native American tribe's DNA) had a close match to that of the Kennewick Man.

So, this explains the answer.
