O If one row of a matrix is a multiple of another row, then the determinant of the matrix is zero.
O If one row of a matrix consists entirely of zeros, then the determinant of the matrix is zero.
O If two columns of a matrix are interchanged, then the determinant of the matrix changes sign.
O If a row of a matrix is multiplied by a scalar, then the determinant of the matrix is multiplied by that scalar.
O none of these
