For(j = 0; j < 7; j++)
Sum = sum + sale[j][3];
B) sum = 0;
For(j = 0; j < 7; j++)
Sum = sum + sale[j][4];
C) sum = 0;
For(j = 0; j < 10; j++)
Sum = sum + sale[j][4];
D) sum = 0;
For(j = 0; j < 10; j++)
Sum = sum + sale[j][3];

Quizplus · Accepted Answer

The correct choice is D because it initializes sum to 0 and correctly iterates over all rows (0 through 9, for a total of 10 rows) of the sale array, summing the elements in the fourth column (index 3, since indexing starts at 0).
