According to liquidity preference theory, a decrease in the price level causes the interest rate to:a. increase, which increases the quantity of goods and services demanded. b. decrease, which increases the quantity of goods and services demanded. c. decrease, which decreases the quantity of goods and services demanded. d. increase, which decreases the quantity of goods and services demanded.

The correct answer is (B)

Explanation:

Liquidity preference theory emphasised on the interest which investors should demand on long-term investments due to the risk they carry. According to liquidity preference theory, a decrease in the price level shifts the money demand curve leftward. A leftward movement of the money demand curve increases the overall quantity demanded. In that regard, a decrease in interest rate increases the demand for goods and services demanded.
