Answer:
The correct answer is deflation. Deflation is the reduction in the price levels. It is the opposite to Inflation. Deflation can occur when the supply of goods is higher than the demand (more things are offered than people want to buy), thus decreasing the price of things. It can also occur when the money supply (the amount of money in an economy) is low, and therefore, each bill and coin has more value and can buy more things.
