Quizplus · Accepted Answer

To find the trade balance, we need to subtract imports from exports for each country grouping. This can be done by subtracting matrix A from matrix B. The resulting matrix will have the same dimensions as A and B, and each element will represent the trade balance for the corresponding country grouping. Therefore, the correct answer is D.
