A plane is landing at an airport. The plane has a massive amount of kinetic energy due to it's motion. When the plane lands, it activates its brakes, causing it to slow down and eventually stop. The kinetic energy that the plane had is now gone. In keeping with the Law of Conservation of Energy, which of the following is the most likely explanation of what happened to that energy?
A. The brakes used a coil system to convert the kinetic energy into potential energy stored in the brakes
B. The kinetic energy of the plane gets pushed into the air in front of it due to drag forces, causing the air to move, thus transferring the kinetic energy from the plane to the air
C. The brakes create friction, which transformed the kinetic energy to heat energy that was dissipated to the surroundings
D. The kinetic energy is being converted into sound energy by the loud engines of the plane
