a. air, wood
b. wood, air
c. soda, air
d. wood, soda

Explanation:

Molecular motion varies with the state of matter. Gases (like air) have highly mobile molecules, liquids (like soda) have more movement than solids (like wood). So, we check which option has a gas (air) and a liquid (soda) compared to a solid (wood).

Answer:

C. soda, air
