What does the kinetic theory explain?

Question 4 options:

Heat is due to Pascal's principle.

Heat is due to temperature.

Heat is due to the motion of molecules.

Heat is due to potential energy.

I believe the correct answer from the choices listed above is the third option. The kinetic theory explains that heat is due to the motion of molecules. Temperature is the measurement used to measure heat and is directly proportional to the average kinetic energy of the molecules.
