Answer:
Option A
Step-by-step explanation:
The savings of all sectors of the economy will always be equal to investment. In macroeconomics, savings and investment are two sides of the same coin. Savings refers to the portion of income that is not consumed or spent, while investment refers to the purchase of new capital goods that are used to produce goods and services. In a closed economy, where there is no international trade, savings and investment must be equal because every unit of currency that is saved must be invested in new capital goods. In an open economy, where there is international trade, savings and investment can differ due to net capital outflows or inflows.
