Final answer:
For National Appliance Corporation (NAC), the crucial considerations for deciding on a manufacturing facility's location should be import quotas, political stability, and currency exchange rates to ensure a stable, cost-effective, and efficient import process for parts.
Step-by-step explanation:
When National Appliance Corporation (NAC) is considering building a new manufacturing facility in Mexico or India, the most important factors to consider would be c) Import quotas, b) Political stability, and d) Currency exchange rates. Import quotas can limit the number of parts NAC can import, affecting the production capacity and cost structure of the manufacturing facility. Political stability is vital for ensuring the long-term sustainability of the facility's operations, investment security, and predictability of business conditions. Currency exchange rates can notably impact the cost of importing parts and the profitability of the facility as it affects the relative price of goods and services between the two countries.
While export subsidies are related to trade barriers, they are more relevant to NAC's decision if the company plans to export appliances from the facility rather than the importation of parts. Therefore, considering import quotas, political stability, and currency exchange rates aligns best with NAC's requirements for building a facility in a cost-effective and low-risk environment.
