Answer:
A. compete against each other in several geographic or product markets.
Explanation:
Different geographic or product markets often possess different challenges for producers to sell their product. This happen because different cultutres, climate, and social conditions tend to create different needs for the customers.
This is why business experts refers to it as 'multi-market competition'. Even though these companies sell similar product, they require different approach/strategies in order to win over different customers in these markets.
