Both use ion channels to move ions across the cell membrane, in or out of the cell. Differences: Passive Transport (or Diffusion) moves ions from high concentration to low, using no metabolic energy. Active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP.
It seems that this question is fairly simple, as you may know kinetic energy is stored and used as potential energy, therefore the answer is B. some of the potential energy is transformed to kinetic energy...
