(C) According to Graham's Law of Diffusion,the rate of diffusion $r$ is inversely proportional to the square root of the molar mass $M$: $r_1 / r_2 = \sqrt{M_2 / M_1}$.Here,$r_{He} / r_{CH_4} = n$,$M_{He} = 4 \ g/mol$,and $M_{CH_4} = 16 \ g/mol$.Substituting the values: $n = \sqrt{16 / 4} = \sqrt{4} = 2$.Therefore,the value of $n$ is $2$.
