Option D correctly uses nested for-loops to iterate through both the main array and its subarrays. The inner loop iterates through each element in the subarray, and the outer loop iterates through the subarrays themselves. This allows for a total to be calculated by adding up all the individual elements within the 2D array. Option A only iterates through the outer array, while options B and C have syntax errors.
