Solution

The correct option is B Decay of a radioisotope
Radiometric dating is utilized to assess the time of rocks and different articles dependent on the settled rot rate of radioactive isotopes. Find out about half-life and how it is utilized in various dating strategies, for example, uranium-lead dating and radiocarbon dating.
So, the correct option is 'Decay of a radioisotope'.
