Respuesta :
is kinetic only. It is only potential when the skateboarder stops or is about to roll down the hill.
As skates is in motion, it has "Kinetic Energy" (Energy by the virtue of object's motion), and potential energy is the energy by virtue of object's height. As, skateboarder skates downhill, height is decreasing so, kinetic energy will increase according to Law of conservation of Energy.
In short, Your Answer would be Option B
