Answer:(B) investment
Explanation:Investment serves as a potential replacement for the leakage of saving. When the leakage of saving at a certain level of GDP exceeds the injection of investment, the total spending (C+I) will be less than GDP, and GDP will not be sustained1. Therefore, investment plays a crucial role in maintaining economic equilibrium. The other options—tax revenues, exports, and government spending—do not directly replace the leakage of saving in the same way that investment does.
