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 BELOW shows this ratio inside the body of three organisms.

C12/C14 Ratio

Organism C12/C14 Ratio
A 1 x 1012
B 2 x 1012
C 4 x 1012



What can most likely be concluded from the info above?

 

 Only Organism A is dead, and Organism C is older than Organism B.

 Only Organism A is dead, and Organism B is older than Organism C. 

Both Organism B and Organism C are dead, but Organism C has been dead longer than Organism B.

 Both Organism B and Organism C are dead, but Organism B has been dead longer than Organism C.
