Correct Answer: exports minus imports

Solution : The correct answer is (a) exports minus imports.

In national income accounting, net exports represent the difference between the value of a country's exports and the value of its imports over a specific period. It is calculated by subtracting the value of imports from the value of exports.

Net exports reflect the net flow of goods and services between a country and the rest of the world. A positive value indicates that the value of exports exceeds the value of imports, resulting in a trade surplus. A negative value indicates that the value of imports exceeds the value of exports, resulting in a trade deficit.
