Solution

The correct option is C $\frac{C_{1}}{C_{2}} = \sqrt{\frac{d_{2}}{d_{1}}}$
Graham's law of diffusion is
$c α d^{- 1 / 2}$
where $c = r m s v e l o c i t y$
$d = d e n s i t y$
$\frac{c_{2}}{c_{1}} = {(\frac{d_{2}}{d_{1}})}^{- 1 / 2}$
or
$\frac{c_{1}}{c_{2}} = {(\frac{d_{2}}{d_{1}})}^{1 / 2}$
so answer is C.
