There are compounds made up of the same elements, like carbon monoxide (CO) and carbon dioxide (CO2). Both compounds are made of carbon (C) atoms and oxygen (O) atoms. However, the ratios of carbon and oxygen in each compound are different. This illustrates the law of multiple proportions.

Understanding the Law of Multiple Proportions
The Law of Multiple Proportions is a fundamental principle in chemistry that states when two elements combine to form more than one compound, the masses of one element that combine with a fixed mass of the other element can be expressed as a ratio of small whole numbers.
Examples of Compounds
In the context of this law, let's analyze the given substances:
Carbon Monoxide (CO) and Carbon Dioxide (CO2)
- Carbon monoxide contains one carbon atom and one oxygen atom.
- Carbon dioxide contains one carbon atom and two oxygen atoms.
- When comparing the ratios of oxygen in these two compounds, we observe that 1 gram of carbon combines with 1.33 grams of oxygen in CO and 2.66 grams of oxygen in CO2.
- The ratio of the masses of oxygen that combine with a fixed mass of carbon (1:2) demonstrates the law effectively.
Other Options Explained
Silver Chloride and Barium Sulfate
- These two compounds do not involve the same elements combining in different proportions.
Sulfur and Sodium
- Sulfur and sodium do not form multiple compounds in a simple ratio relationship.
Sodium Chloride and Cupric Oxide
- This pair also involves different elements and does not illustrate the law effectively.
Conclusion
Thus, the correct answer is option 'A', as carbon monoxide and carbon dioxide are two compounds formed by the same elements (carbon and oxygen) that follow the law of multiple proportions. This principle is crucial for understanding chemical composition and reactions.
