Kinetic energy is defined as the form of energy that an object or a particle possesses due to its motion.
In state A, the particles are very closely packed and have very little room to move around.
In state B, the particles are less closely packed and have more room to move around.
In state C, the particles are least closely packed, and can move around more freely of the all three states.
Since kinetic energy is the energy possessed by a body due to its motion, the order of kinetic energy of particles is:
State C > State B > State A
Therefore, the kinetic energy of particles of state B is less than that of state C and more than that of state A
