Answer:
D) it presumes there will be economic gains even if output does not become internationally competitive
Step-by-step explanation:
The argument for import protection in developing countries to bring about industrialization differs from the infant-industry argument in that it presumes there will be economic gains even if the output does not become internationally competitive. International competitiveness is a step of the relative cost of services/goods from a nation. Countries that can provide a similar quality of goods at a cheaper cost are stated to be extra competitive.
