Answer: a. Inflation
Step-by-step explanation:
Inflation refers to the general rise in prices of items in an economy in a certain period of time. Inflation essentially erodes the value of the domestic currency of the economy in question.
Central Banks like the Fed can use Monetary policy to influence inflation. In this case they reduced the amount of money in the economy by reducing bank loans. This will ensure that people cannot spend too much which would increase demand and therefore increase prices.
By doing this, they have limited the likelihood of inflation.
