Darina [25.2K]3 years ago
4 0

Answer: Option (1) and (3)

Explanation: Radiometric dating is a very efficient method of dating a rock or fossil or any object. It helps in determining the estimated age of that particular object.

The half-life of all the radioactive methods are already known, so it becomes easy to determine how much decay an object has undergone. So by knowing the rate at which the decay occurs, one can find out the approximate age by using the radioactive decay formula.

Thus, the correct answer is option (1) and (3).
