Which observation illustrates the law of conservation of mass?

The C:O mass ratio of a particular compound is the same, regardless of the size or source of the sample.

When 3 g of carbon reacts with 8 g of oxygen, 11 g of carbon dioxide is produced.

The C:O mass ratio of one compound is exactly double that of another compound.

Burning 10 g of propane produces twice as much carbon dioxide as burning 5 g of propane.

I think the correct answer among the choices listed above is the second option. The observation which illustrates the law of conservation of mass is that wh en 3 g of carbon reacts with 8 g of oxygen, 11 g of carbon dioxide is produced. Other choices doesn't shows that mass in is equal to the mass out.
