Answer:
The answer is: B) Banks will increase their nominal interest rates
Step-by-step explanation:
If the nominal interest rate is 6% and the inflation rate is 2%, then the real interest rate will be 4%. If the inflation rate is expected to increase to 4% (a 2% increase), banks will usually increase their nominal interest rate in the same proportion (a 2% increase) so the new nominal interest rate would be 8%. This is done in order to keep the real interest rate stable.
