Which Statement Is True

Which statement is true?

A) Molecules in gases possess kinetic energy because they are in constant motion, while molecules in liquids and solids are not in constant motion and hence possess no kinetic energy.
B) Molecules in gases and liquids possess kinetic energy because they are in constant motion, while molecules in solids are not in constant motion and hence possess no kinetic energy.
C) Molecules in gases, liquids and solids possess kinetic energy because they are in constant motion.
D) Polyatomic molecules possess kinetic energy in the liquid and gaseous states because the atoms can move about in the molecule even if the molecule cannot move.
E) Because solids are rigid, their molecules do not possess kinetic energy unless the solid is melted.
