Correct option is B
Ex Ante refers to plans or intentions before they are realized, particularly in economic contexts. Thus, (A) Ex Ante Saving represents what is actually planned to save is correct because it refers to the amount of savings planned or intended by economic agents before the actual saving occurs.
Ex Post refers to outcomes or results that are observed after the event has occurred. Therefore, (C) Ex Post Saving depicts what has actually happened is correct because it measures the actual amount of savings realized after all transactions are completed. It reflects the real outcome as opposed to the planned outcome.
