Which statement explains why carbon-14 dating Cannot be used to date ancient rocks

The answer is the radioactive isotope reacts in the same way as stable isotopes in the chemical reactions in the body.

C-14 and C-12 are carbon isotopes used to measure the approximate age of organic remains. C-12 is stable, and it does not break down into other elements over time. C-14 is not stable. It breaks down into N-14. But, in the body, the radioactive isotope reacts in the same way as stable isotopes in the chemical reactions.
