Answer:
The correct answer is option D.
Step-by-step explanation:
As the price level decreases, the purchasing power of money increases. Or in other words, the real value of cash balances will increase.
This implies that consumers will need lesser money to purchase more goods and services. As a result, the total expenditure will increase.
An increase in the price level, on the other hand, will cause the purchasing power and real value of money balances to decrease. As a result, the total expenditure will decrease.
