The correct answer is A. Ice, water, steam
Explanation:
The arrangement of molecules in substances is widely influenced by the state of the matter of the substance. In this way, in solids the molecules have a fix organization and are closely packed due to this, solids have both a defined shape and volume; in liquids the molecules are still close to each other but there is no a defined structure and therefore liquids have a defined volume but not a defined shape; finally, in gases molecules do not follow an orderly arrangement and there is more space between them which makes them not have a define volume or shape.
According to this, the one with the most ordered arrangement is ice because this is solid, then this is followed by water in the liquid state and finally by steam in the gas state which is the one with least orderly arrangement of molecules.
