Vedclass · Answer

(B) Potassium-argon $(K-Ar)$ dating is a radiometric dating method used to determine the age of rocks and minerals. It relies on the radioactive decay of potassium-$40$ $(^{40}K)$ into argon-$40$ $(^{40}Ar)$. The half-life of potassium-$40$ is approximately $1.3 	imes 10^9$ years. Due to this long half-life,this method is particularly effective for dating very old geological samples,such as those that are billions of years old,rather than very young fossils. Among the given options,$2$ billion years is the most appropriate range for this technique.

Potassium-argon dating can determine the age of fossils that are:
