According to Graham's law, at a given temperature, the rate of diffusion \( r_{A} / r_{B} \) of gases \( A \) and \( B \) is given by:
(A) \( \left(P_{A} / P_{B}\right)\left(M_{A} / M_{B}\right)^{1 / 2} \)
(B) \( \left(M_{A} / M_{B}\right)\left(P_{A} / P_{B}\right)^{1 / 2} \)
(C) \( \left(P_{A} / P_{B}\right)\left(M_{B} / M_{A}\right)^{1 / 2} \)
(D) \( \left(M_{A} / M_{B}\right)\left(P_{B} / P_{A}\right)^{1 / 2} \)
