What is the relationship between the molecular forces in a solid, liquid, and gas?

The molecular forces are strongest in solids, weaker in liquids, and very weak in gases. (correct)
The molecular forces are equal in all three states of matter.
The molecular forces are weakest in solids, stronger in liquids, and strongest in gases.
The molecular forces are unpredictable and vary randomly between the three states of matter.
