Suppose the coefficient matrix of a system of linear equations has a pivot position in every row. Explain why the system is consistent. Choose the correct answer below. O A. The system is consistent because all the columns in the augmented matrix will have a pivot position. B. The system is consistent because the augmented matrix is row equivalent to one and only one reduced echelon matrix. O C. The system is consistent because the augmented matrix will contain a row of the form O .. 0 b with b nonzero. D. The system is consistent because the rightmost column of the augmented matrix is not a pivot column.
