Determine if the columns of the matrix span R CAED Select the correct choice below and fill in the answer box to complete your choice OA. The columns do not span R* because none of the columns of A are linear combinations of the other columns of A which has a pivot in every row B. The columns span R* because the reduced echelon form of the augmented matrix is (Type an integer or decimal for each matrox element.) C. The columns span R* because at least of the columns of A is a linear combination of the other columns of A OD. The columns do not span R* because the reduced echelon form of the augmented matrix is (Type an integer or decimal for each matrix element) which does not have a pivot in every row -21-615-39 -5-34-12 16 30-6 42 21-27-6-18
