Answer:
The correct answer is - light and thermal energy.
Explanation:
When a log sets on fire it starts burning and the potential energy which is stored in the log as the chemical energy is released. The energy that is released in the burning process is kinetic energy.
This released kinetic energy is released in two forms from potential energy by the heat that is thermal energy and the other is light energy which one can see as flames of fire.
Thus, the correct answer is - light and thermal energy.
