Answer: C.
Explanation: Water (H2O) is a chemical compound with a fixed 2:1 ratio of hydrogen to oxygen and has different properties than its elements. A mixture of hydrogen and oxygen is a physical blend of H2 and O2 gases, so the proportions can vary and the individual gases retain their own properties.
