\mathrm{r_n=0.529 \times 10^{-10} \frac{\left(3^2\right)}{1} m}

\mathrm{r_3=4.76 \times 10^{-10}}

\mathrm{V_3=2.18 \times 10^{6}(\frac{1}{3})=0.73\times10^{6}m/s}

\mathrm{\text { frequency }=\frac{V_3}{2 \pi r_3}}

                        \mathrm{=\frac{0.73\times10^{6}}{2\pi\times 4.76\times10^{-10}}} \

                    \mathrm{v=2.4\times10^{14}Hz}

Option (4) is the correct answer.
