Answer:
Option-(A): The beaker is the waves of the ocean which approaches the shore, as the top of the wave curls over and crashes into the sand, as this wave with a curled top is called a plunging.
Step-by-step explanation:
As the waves generated inside the oceanic region consists of an enormous amount of potential energy in due to the fact that the waves are generated by the water molecules present in high level inside the water reservoir or mainly the oceans, as the waves when crashes into the shores then the whole amount of energy (which is the potential energy) and then the direction of the wave also changes,along with it the amount of energy is changed into the dynamic form of energy. As the waves comprises of having more height with it, as the whole structure of the wave posses more unique features.
