True or False please explain

Exercise 5.2.1: Cofactor expansions. 0 About Determine whether the statement is true or false. Justify each answer or provide a counterexample when appropriate. (8) The most efcient way to compute the determinant of 0 1 3 A = 2 3 5 is to find the cofactor expansion along row 2. 0 6 1 For any square matrix A, Cij = 035. The determinant of any triangular matrix containing a 0 on the main diagonal is 0. The determinant of a 4 x 4 matrix can be used to determine if four points are coplanar and to find the equation of a plane that goes through four points. The determinant can be used to find the equation of an ellipse given ve distinct points on the ellipse
