\mathrm{R=R_0 A^{1 / 3} }

\mathrm{ \therefore \frac{R\left(\mathrm{Au}^{197}\right)}{R\left(\mathrm{Ag}^{107}\right)}=\left(\frac{197}{107}\right)^{1 / 3}=(1.841)^{1 / 3} }

\mathrm{=\operatorname{antilog}\left[\frac{1}{3} \log (1.841)\right]=\operatorname{antilog}\left[\frac{1}{3} \times 0.2650\right] }

\mathrm{=\operatorname{antilog}(0.08833)=1.225}

Hence option 3 is correct.
