D, the country GDP will tend to be equal to its domestic income.

Gross National Product (GNP) measures the total value of goods and services produced by a country’s residents, including those produced abroad. Gross Domestic Product (GDP), on the other hand, measures the total value of goods and services produced within a country’s borders, regardless of the nationality of the producers.

If no foreign company produces in a country but many of the country’s companies produce abroad, it means that the country’s residents are earning income from their foreign production activities. This income will be included in the country’s GDP, as it represents domestic production. Therefore, the country’s GDP will tend to be equal to its domestic income.
