C Correct answer
Explanation

Carbon-14, a radioactive isotope of carbon, is used in radiocarbon dating to determine the age of organic materials up to about 50,000 years old. The amount of Carbon-14 remaining in a sample indicates how long it has been since the organism died. Hydrogen, gold (Aurum), and sulfur do not have suitable radioactive isotopes for dating.
