Question

Studying the decay of radioactive isotopes in dead organisms helps scientists to identify fossilized remains. The ratio of C-12 to C-14 in the atmosphere is 1 x 1012. The table shows this ratio inside the body of three organisms.
C12/C14 Ratio
Organism C12/C14 Ratio
E 8 x 1012
F 1 x 1012
G 4 x 1012


What can most likely be concluded from the above information?
Only Organism F is alive, and Organism G died before Organism E.
Only Organism F is alive, and Organism E died before Organism G.
Only Organism E is alive, and Organism G died before Organism F.
