Two elements X and Y have atomic weight ...

Two elements `X` and `Y` have atomic weight of `14` and `16`. They from a series of compounds `A,B,C,D and E` in which the same amount of element `X,Y` is present in the ratio `1:2:3:4:5`. If the compound `A` has `28` parts by weight of `X` and `16` parts by weight of `Y`, then the compound of `C` will have `28` parts weight of `X` and

A

32 parts by weight of Y

B

48 parts by weight of Y

C

64 parts by weight of Y

D

80 parts by weight of Y
