### Question

An element $$\text{X}$$ forms the following oxides $$\text{X}_2\text{O}, \text{XO}$$ and $$\text{XO}_2.$$ This phenomenon illustrates the law of ________.

B)
Definite proportion
C)
Mass action
D)
Multiple proportion

The correct answer is D.

X is not fixed except if you are considering X2O and XO where O will be fixed or better still let it be X2O,XO and X3O where O is fixed and X is in multiple proportion
