Answer:
The correct answer is letter "A": It will decrease.
Step-by-step explanation:
Price floors are price levels the government of a country sets to protect the price of a good will not fall to a level in which producers will not be able to make profits. Since the price level is unlikely to fall, over the years consumers will lose interest in that product and start looking for a substitute at lower prices. The quantity demanded of the price-floor good drops under that scenario.
