Answer:
The correct answer is letter "B": predatory pricing.
Explanation:
Predatory pricing refers to companies setting prices below the average level in an attempt to wipe out competition. In the beginning, consumers may benefit from the low prices but after the competition has disappeared, the predatory company raises the prices, but, in this scenario, consumers do not have substitutes from where to choose. The predatory company became a monopoly.
Predatory pricing practices are forbidden by the Federal Trade Commission (FTC) in the U.S.
