Answer: A.Many countries still have rules governing the competitive marketplace, including those that affect pricing.
Explanation:
Determining the selling price in the global marketplace can be an extremely difficult task because many countries still have rules governing the competitive marketplace, including those that affect pricing.
A example of this is the situation with nations that possess weak currencies, such economies typically surplus labor which can lead to their products being cheaper in global markets.
Also, some nations try to protect their local industries and therefore use several methods like tariffs, quotas, ban on certain goods etc. These all have effects on the pricing of the goods.
