A and B are n×n matrices. Check the true statements below: A. The determinant of A is the product of the pivots in any echelon form U of A, multiplied by (−1)r, where r is the number of row interchanges made during row reduction from A to U. B. det(A+B)=detA+detB. C. If the columns of A are linearly dependent, then detA=0. D. Adding a multiple of one row to another does not affect the determinant of a matrix.
