Answer: the correct option is A.
Explanation: First, we will define International Strategy and Global-standardization strategy.
International strategy refers to a business plan or strategy that is created by a company to do its business in foreign markets. This strategy requires analyzing the international market, defining goals, understanding market dynamics & develop offerings that are peculiar to each foreign market.
Global standardization is the strategy of using standard marketing internationally. What this means is that, it is the ability of a company, business or organization to use the same marketing strategy from one country to the next, and across various cultures.
From the above definitions, we can conclude that a Global standardization strategy is more cost efficient, because there is no case repeating the same marketing strategy cost. This will therefore ensure that cost is kept low and at a minimum.
