Quizplus · Accepted Answer

Carbon-14 dating is only effective up to approximately 50,000 years old, so the best choice is D, "tens of thousands." A is incorrect because millions of years would require other radiometric dating methods. B is incorrect because billions of years would require other methods such as uranium-lead dating. C is too broad and covers a range of time that is beyond the scope of carbon-14 dating.
