Answer:
d. the interest rate adjusts to balance the supply of, and demand for, money.
Step-by-step explanation:
In Keynes's view, the interest rate is the premium that economic agents get for delaying the consumption that satisfies them. This is why people decide to save rather than consume. Thus, the consumer decides between present consumption or future consumption, depending on the attractiveness of the interest rate practiced in the market. In other words, the interest rate acts as the beacon between supply and demand for money. When the interest rate is attractive, savers forgo current consumption and save for extra income.
