The main job of an archaeologist is C. To study history through artifacts.

Archaeologists frequently go to locations where key historical events have occurred, and go on what are called "archaeological digs". These digs are helpful for finding fossils, remains, or artifacts that previous people may have used. These pieces are helpful in indicating things about the culture and the way of life of many people who came before us, and allow for historians to infer many things about history.

Hope this helps!
