Which is an aspect of the kinetic-molecular theory and can be used to explain the behavior of plasmas?

Kinetic-molecular theory describes particles as moving and exchanging energy through collisions. In an elastic collision, total kinetic energy is conserved, though it can pass from one particle to another; this also applies to the charged particles in a plasma. Choice D, “Particles exchange energy through elastic collisions,” is correct. The other choices either describe solids or contradict the relationship between temperature and particle kinetic energy.
