(B) From the ideal gas equation,$PV = nRT$,where $n = \frac{m}{M}$ and $d = \frac{m}{V}$.Thus,$P = \frac{dRT}{M}$.For gases $A$ and $B$ at the same temperature $T$,the ratio of pressures is given by:$\frac{P_A}{P_B} = \frac{d_A}{d_B} \times \frac{M_B}{M_A}$.Given: $d_A = 4 d_B$ and $M_A = 0.5 M_B$ (or $M_B = 2 M_A$).Substituting these values:$\frac{P_A}{P_B} = \frac{4 d_B}{d_B} \times \frac{2 M_A}{M_A} = 4 \times 2 = 8$.
