Answer:
A.rose making the interest rate fall
Step-by-step explanation:
According to the liquidity preference theory developed by John Keynes, if the money supply rises, price level also rises, interest rate falls. If interest rate falls, the price of bond rises which would increase capital gains. People would prefer to hold bonds instead of money, therefore, investment spending would rise.
The liquidity preference theory states that we hold money for transactive, speculative and precautionary motives.
