The ratio of radioactive atoms to other kinds of atoms changes over time. Hence, option C is correct.

What is radioactive decay?

In the process of radioactive decay the unstable atom nuclei of the parent nucleus break down and split so as to release the daughter atoms or nuclei along with the release of energy in the form of heat. Thus as the decay process proceeds the concentration of the parent atom decreases but the concentration of the daughter atom increases.

Radioactive atoms can be used to date materials because the radioactive decay occurs at a known rate, and the density of fission tracks for the amount of uranium within a mineral grain can be used to determine its age.

Hence, option C is correct.
