Which of the following pairs can be cited as an example to illustrate the law of multiple proportion?

The law of multiple proportions say that If two elements form more than one compound between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers.

In option(B), The ratio of the masses of oxygen that can react with carbon=1:2

In Option(C), The ratio of the masses of oxygen that can react with sulphur = 2:3.
