Correct answer and explanation

Correct answer: Carbon-14

Explanation: āœ… Correct Answer: C) Carbon-14 šŸ“š Explanation: Carbon-14 is a radioactive isotope that is constantly absorbed by living organisms from the atmosphere. When an organism dies, it stops taking in Carbon-14, and the existing amount begins to decay at a known rate (half-life of approximately 5,730 years). By measuring the remaining Carbon-14, scientists can estimate how long ago the organism lived.
