The correct answer is - E.) to increase national sovereignty.
By cooperation on regional or global level the states do not, and can not really do anything about increasing the national sovereignty. The reason for that is that the national sovereignty is the matter of the state itself, its politics, policies, and handling of the situations in the country. The other countries with whom the state cooperates have nothing to do with it, nor it is their place to interfere in the national sovereignty of the other states, be it friendly states or not.

Explanation:
The Heckscher-Ohlin model refers to an economic theory which states that countries will export the goods that they can produce efficiently and in large quantities while they'll import those that they are less efficient in producing.
According to the H-O theorem, the pattern of trade that exists between countries as a result of the characteristics that are possessed by the countries. In such case, a capital-abundant country can produce a capital intensive good efficiently and therefore should export the capital intensive good. Likewise, a labor-abundant country can produce labor intensive good efficiently and therefore should export the labor-intensive good.
The answer to this is probably their ability to absorb heat. Oceans are great at absorbing heat from the sun and storing it. If they were bad at it, the heat would be trapped due to the greenhouse effect and the climate would become scorching hot. This way, oceans absorb large amounts of heat and effectively reduce the overall temperature of the world.
