In the equation of exchange (MV = PQ), if V (velocity of money) and Q (quantity of goods and services) are constant, then changes in the money supply (M) will directly lead to proportional changes in the price level (P).

wenxinyiyan A. changes in the price level must be proportional to changes in the money supply.

Explanation:
The equation of exchange, also known as the quantity theory of money, is typically expressed as MV = PQ, where:

* M is the money supply
* V is the velocity of money (the average frequency with which a unit of money is spent in a given time period)
* P is the price level
* Q is the quantity of goods and services transacted

If V (velocity) and Q (quantity of goods and services) are constant, then any change in M (money supply) will directly and proportionally affect P (price level). This is because, with V and Q being constant, the equation simplifies to a direct relationship between M and P.

In other words, if the amount of money in circulation increases while the speed of money circulation and the amount of goods and services being transacted remain the same, prices will rise proportionally to the increase in the money supply. Conversely, a decrease in the money supply will lead to a proportional decrease in prices.

zhipu A. changes in the price level must be proportional to changes in the money supply.

The equation of exchange is given by MV = PQ, where M is the money supply, V is the velocity of money, P is the price level, and Q is the quantity of goods and services produced (real GDP). If V (velocity of money) and Q (quantity of goods and services) are constant, any change in the money supply (M) must result in a proportional change in the price level (P) to maintain the equality. Hence, the correct answer is A.
