(C) Given: $d_A = 2d_B$ and $M_A = 0.5M_B$ (or $M_B = 2M_A$).Using the ideal gas equation: $PV = nRT = \frac{m}{M}RT$.Rearranging for pressure: $P = \frac{m}{V} \cdot \frac{RT}{M} = \frac{dRT}{M}$.Since temperature $T$ is constant,the ratio of pressures is $\frac{P_A}{P_B} = \frac{d_A}{d_B} \times \frac{M_B}{M_A}$.Substituting the given values: $\frac{P_A}{P_B} = \frac{2d_B}{d_B} \times \frac{2M_A}{M_A} = 2 \times 2 = 4$.
