The radioactivity due to Carbon-14 measured in a piece of a wooden casket from an ancient burial site was found to produce 20.0 counts per minute from a given sample,
 
  whereas the same amount of carbon from a piece of living wood produced 160. counts per minute. The half-life of Carbon-14, a beta emitter, is 5730. years. Thus we would estimate the age of the artifact to be about
  A) 14,800 years
  B) 20,000 years
  C) 5,700 years
  D) 17,200 years
