Carbon 14 dating method is based on the fact thatA. carbon 14 fraction

1.	Carbon 14 dating method is based on the fact thatA. carbon 14 fraction is same in all objectsB. carbon 14 is hightly insolubleC. ratio of carbon 14 and carbon 12 constantD. All of the above
Answer» Correct Answer - C 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)`
