A `V dm^(3)` flask contains gas `A` and another flask of `2V dm^(3)` contains gas `B` at the same temperature. If density of gas `A` is `3.0g//dm^(-3)` and of gas `B ` is `1.5 g dm^(-3)` and mol. Wt. of `A=(1)/(2)` mol. Wt. of `B`, then the ratio of pressure exerted by gasses is `-`

A

`( P_(A))/( P_(B)) = 2 `

B

`( P_(A))/( P_(B)) = 1`

C

` ( P_(A))/( P_(B)) = 4 `
