The given declaration does not include any information about the size of the array "sale", so we cannot assume it has 10 columns. Therefore, options C and D are incorrect. The question explicitly asks for the sum of the elements of the fifth row of "sale", so option A, which sums the elements of the sixth row, is also incorrect. Therefore, the only correct answer is option B, which sums the elements of the fifth row.
