Correct answer and explanation

Correct answer: C₆¹⁴

Explanation: ✅ Correct Answer: B. C₆¹⁴ 📚 Explanation: Carbon-14 (C-14) is a radioactive isotope of carbon used in 'radiocarbon dating' to determine the age of organic archaeological findings. This technique is based on the decay rate of C-14 over time. It is effective for dating objects like old wood, bones, and plant remains that are up to 50,000 years old. This discovery was a breakthrough for modern archaeology and history.
