Explanation of Solution

A decrease in the interest rate reduces the cost of borrowing, which in turn increases the level of investment. The increase in investment increases the employment, income, and output. Since the income increases, the purchasing power also increases, thereby increasing the consumption. Thus, the decreasing interest rate will increase the investment, consumption, and GDP.
