Answer:
The correct option is is A, predatory pricing
Step-by-step explanation:
Predatory pricing is an illegal approach to pricing where a firm fixes a very low price in order to send competitors out of business.
This is very applicable to a firm that has economies of scale where its cost per unit reduces as more and more units are produced, making it possible to undercut competitors without feeling much impact in profitability.
This approach is against the anti-trust law as it paves for a monopoly market,where only one firm operating in the market determines the price which is not likely to be favorable to consumers
