What are the two main types of energy? potential and electrical radiant and kinetic electrical and thermal kinetic and potential

Option D, kinetic and potential

Explanation:

There are mainly two forms of energy – kinetic and potential energy. Rest all other forms of energies falls into these two categories. Kinetic energy is associated with the movement of an object while potential energy is the energy possessed by an object by virtue of height at which it is placed.  

For example – thermal energy is due to the motion of particles (which are in excited mode)  

Hence option D is correct.
