Which of the following pairs of compounds cannot demonstrate the law of multiple proportions?

Ammonia contains $82.35\%$ nitrogen and $17.65\%$ hydrogen. Water contains $88.90\%$ oxygen and $11.10\%$ hydrogen. Nitrogen dioxide contains $63.15\%$ oxygen and $36.85\%$ nitrogen. Which law can be illustrated by the given data?

Assertion : Atoms can neither be created nor destroyed.
Reason : Under similar conditions of temperature and pressure,equal volumes of gases do not contain equal numbers of atoms.
