Carbon 14 dating method is based on the fact that

Options

A. carbon 14 fraction is same in all objects
B. carbon 14 is hightly insoluble
C. ratio of carbon 14 and carbon 12 constant
D. All of the above

Answer

C

Explanation

By carbon dating method
Age of wood =`(2.303)/(0.693)xxT_(0.5) log(N_(0))/(N)`
Where , `(N_(0))/(N)=[("Ratio of" C^(14)//C^(12)"in living wood")/("Ratio of" C^(14)//C^(12) "in dead wood")]`
Hence it based upon the ratio of `C^(14)` and `C^(12)`
