Kinetic energy
electromagnetic energy
Raidiation
Light travels as light energy. Light is a type of electromagnetic wave.
It is a very simple observation to tell that an electron can drop from one energy level to another. Electrons always want to be at the lowest energy, but to get to allowed energy level they need to lose energy. Electrons release energy in the form of photons of the same amount of energy as the energy level change. We can observe the light released when we put energy into a system and match the energy of the light to steps an electron takes down the energy level.
A is wrong. B is right C is right D is wrong A: Sound travels as a wave, therefore it does not travel in a straight line. B: Sound travels in a wave. C: The sound wave is a form of energy; all waves are. D: Sound cannot travel in a vaccuum. A is not entirely wrong.

Raidiation
When an atom releases energy in the form of visible wavelengths of light, it indicates that an electron in that atom has gone from an excited energy level, back down to a lower energy level.

Thermal energy is also known as heat energy. It is a form of energy which travels due to the temperature gradient.
Light travels as light energy. Light is a type of electromagnetic wave.
