Answer: a. I and II only
Step-by-step explanation:
Money is neutral which means that even if you change to supply of money in an economy, it will not translate to an increase in GDP because only the nominal values of things will change (as a result of inflation) while the real values of things like GDP will remain the same.
Increasing the growth of money supply by printing money would also cause inflation in the long run because the money will lose its value like goods do when their supply is increased even though demand does not. A weaker currency needs more units to buy a good which is where the inflation will come from.
