Which of these expressions is correct?

Correct option is A

The correct answer is (a) If the factor income from abroad is greater than the factor income paid abroad, then GNP would be greater than GDP
Explanation: Gross National Product (GNP) is the total market value of all the products and services produced in one year by labor and property supplied by the citizens of a country. Unlike Gross Domestic Product (GDP), which defines the economic output within the geographical confines of a country, GNP includes net income from abroad—this includes incomes earned by residents from overseas investments minus the income earned within the domestic economy by overseas residents.
 If the factor income from abroad (income earned by residents from overseas investments) is greater than the factor income paid abroad (income earned by non-residents within the country), the net factor income from abroad is positive.
 Adding this positive net factor income to GDP (which measures the domestic production) results in a GNP that is greater than GDP.
