A `0.5 dm^3` flask contains gas A and 2 `dm^3` flask contains gas B at the same temperature. If density of A = `4 g/`dm^3`, that of B = `2 g/dm^3` and molar mass of A is half of that of B, then the ratio of pressure exerted by gas is

A

`P_A / P_B = 0.5`

B

`P_A / (P_B) = 2`

C

`P_A / (P_B) = 4`

D

`P_A / (P_B) = 0.25`
