A ray of light with wavelength $\displaystyle \lambda$ is incident on three different photoelectric cells namely $\displaystyle 1$, $\displaystyle 2$ and 3. The threshold wavelength of these photoelectric cells are $\displaystyle \lambda_1, \lambda_2$, and $\displaystyle \lambda_3$, respectively and the magnitude of stopping potentials of these cells are $\displaystyle \mathrm{V}_1$, $\displaystyle \mathrm{V}_2$ and $\displaystyle \mathrm{V}_3$, respectively. The relation between $\displaystyle \lambda$ and threshold wavelengths are $\displaystyle \lambda_1<\lambda, \lambda_2>\lambda$ and $\displaystyle \lambda_3 \gg \lambda$. The correct option is :
