The correct answer is: C. Developments in national and international markets
An export surplus is a situation in which a country exports more goods and services than it imports. This can happen for a number of reasons, including:
- A country may have a comparative advantage in the production of certain goods or services. This means that it can produce those goods or services more efficiently than other countries.
- A country may have a strong currency, which makes its exports more competitive in international markets.
- A country may have a favorable trade policy, which makes it easier for businesses to export their goods and services.
- Developments in national and international markets can also lead to an export surplus. For example, if there is a sudden increase in demand for a country’s exports, this can lead to an increase in exports and a decrease in imports.
Option A, Country’s exports promotion value, is not the most appropriate cause of export surplus. While a country’s exports promotion value can certainly contribute to an export surplus, it is not the only factor that determines whether or not a country will have a surplus.
Option B, Country’s stringent import policy, is also not the most appropriate cause of export surplus. While a country’s import policy can certainly affect the amount of goods and services that it imports, it is not the only factor that determines whether or not a country will have a surplus.
Option D, None of the above, is also not the correct answer. As explained above, there are a number of factors that can contribute to an export surplus, including developments in national and international markets.
