Answer
C and D
Step-by-step explanation
A is NOT correct, Solids have the strongest intramolecular forces.
B is NOT correct, Gases have more kinetic energy than liquids.
C is correct, Solids have the lowest kinetic energy.
D is correct, The particles in a gas do not have any particular arrangement and there are very, very weak forces between them. So, the particles in a gas can easily move around and fill the shape of the container they are in, meaning they have no fixed shape.
