Two different oxides of manganese are compared in the table shown below.

Color Percent $Mn$ (by mass) Percent $O$ (by mass)
Oxide #1 Black 63.19 36.81
Oxide #2 Dk Green 77.50 22.50

$$$$
When substituted for X and Y in the fraction below, which of the following pairs CORRECTLY gives a result that illustrates the Law of Multiple Proportions?

$$\cfrac { \cfrac { 63.19 }{ X } }{ \cfrac { 77.50 }{ Y } } $$

A

X = 54.94
Y = 54.94

B

X = 36.81
Y = 22.50

C

X = 16.00
Y = 16.00

D

X = 22.50
Y = 36.81
