Concept:Kinetic theory explains the behaviour of particles in matter, such as motion, collisions, and changes in arrangement.Explanation:Change of state is explained by kinetic theory because it involves changes in particle energy and arrangement.Diffusion is explained by kinetic theory because it results from the random motion of particles.Osmosis is explained by kinetic theory because it involves the movement of solvent particles through a membrane.Radiation is not explained by kinetic theory because it transfers energy by electromagnetic waves, not by particle motion.Answer:I, II and IV — Option D.
