Answer:
b. has a comparative advantage in producing kiwis.
Step-by-step explanation:
Competitive advantage can be defined as conditions, factors or circumstances that allow a business firm (organization) to manufacture finished goods or services better and perhaps cheaper than other (rival) firms in the same industry. Thus, it's responsible for putting a business firm in a superior or more favorable position than rival firms.
This ultimately implies that, a competitive advantage has a significant impact on a business because it increases its level of sales, revenue generation and profit margin when compared to rival firms in the same industry.
In this scenario, New Zealand has a comparative advantage in producing kiwis than Australia because it uses one unit of labor to produce a kiwi and two units of labor to produce an apple
