Answer:
Correct Answer: 2.(c)
Solution:
(c) By carbon dating method
$ \text{Age of wood} = \frac{2.303}{0.693} \times t _{1/2} {~log} (\frac{N_0}{N}) $
$ \hspace{30mm} \Big[ \frac{{~ratio} {~of} {~C^{14}/C^{12}} {~in} {~living} {~wood}}{{~ratio} {~of} {~C^{14}/C^{12}} {~in} {~dead} {~wood}} \Big] $
Hence, it is based upon the ratio of $C^{14}$ and $C^{12}$.
