Took a wild guess and got it correct. The answer is B Kinetic Energy increases and potential energy decreases.

<span>At first when the car is at the datum point where is no elevation, the kinetic energy increases while the potential energy is zero. As it travel the path and goes upward the kinetic enrgy decreases while the potential energy increases. When it goes down again the kinetic enrgy increases again while the potential energy decreases </span>
