An archeological artifact was subjected to radiocarbon dating. The artifact showed a carbon-14 decay rate of 12.2disintegrations/min per gram of carbon. Carbon-14 has a half-life of 5715 years, and currently living organisms decay at the rate of 15.3 disintegrations/min per gram of carbon. What is the approximate age of the artifact? Select one: A. 371 years old B. 6597 years old C. 851 years old D. 1867 years old
