Answer:
b. Maintaining robust Chinese exports and a favorable balance of trade for China
Step-by-step explanation:
If the currency of a country is "undervalued," the cost it can be traded for other foreign currencies is too small.
A weak national currency boosts the country's exports on world markets and also increases the cost of imports. Higher volumes of exports spawn economic growth, while priced imports have the same impact as domestic equivalents to imported goods are opted by consumers rather than the pricy import.
