Answer :

Answer D because energy is always around us, for it cannot be created nor destroyed

Energy changes constantly through transformation. According to the law on the conservation of energy in physics and chemistry, the total energy of the system remains the same, it is preserved over time. It can neither be created nor destroyed, it can only be transformed, or transferred from one form to another. So we have circulation, the flow of energy, because of its constant transformation.
