In a two-dimensional array, each row is an array itself. So to get the length of a specific row, we need to access that row first using its index and then get the length of that row. Therefore, we can use the notation "numbers[r].length" to obtain the length of row r. Option A gives the length of the entire two-dimensional array, while option B and C are not syntactically correct or logical for getting the length of a specific row.
