assign6: Problem 9 (1 point) A and B are n x n

assign6: Problem 9 (1 point) A and B are n x n matrices. Check the true statements below: A. If det A is zero, then two rows or two columns are the same, or a row or a column is zero. B. If two row interchanges are made in succession, then the determinant of the new matrix is equal to the determinant of the original matriz C. The determinant of A is the product of the diagonal entries in A. D. det AT = (-1) det A.
