Answer:
A) Predatory pricing
Step-by-step explanation:
Predatory pricing consists in first: setting a very low price for the product, so that customers are gained, and competitors are driven out of the market, and second, once competitors are no longer in the market, raising the pricing to a more profitable level.
Predatory pricing is illegal in many countries, for example, in Germany, because it is considered an unfair form of competition.
