Answer:
The correct answer is C. Radioactive dating is a way to determine the age of a fossil by comparing the number of stable isotopes to the number of unstable isotopes using a known half-life.
Explanation:
Radiometric dating or radioactive dating is the determination of the age of an object from the radioactive substances contained therein and the products of radioactive decay. This dating process is based on the tendency of certain atoms of chemical elements to emit particles and radiation from their unstable nuclei. This emission is called radioactivity.
When a radioactive nucleus disintegrates, the products formed may be unstable, later disintegrating to a balance. Nuclear transformation is called radioactive decay.
