The following assumptions indicate the weaknesses of the Heckscher- Ohlin Theory:

• Two countries, two commodities and two factors of production
• Technology is the same in both countries.
• One of the commodities is labor-intensive and the other one is capital-intensive in both countries.
• One of the countries is labor-abundant and the other one is capital-abundant (not both of the countries are labor-abundant).

The correct answer is D.
