A is true (standard determinant property). B is true (definition of minor). C is false (not skew-symmetric). D is true (A+A′ is always symmetric). E is false (∣A∣=0 means singular). Correct statements: A, B, D.
Choose the correct statement A. If any two rows or any two columns are identical or proportional, then value of determinant is Zero. B. Minor of an…

Choose the correct statement
A. If any two rows or any two columns are identical or proportional, then value of determinant is Zero.
B. Minor of an element aij of the determinant of matrix A is the determinant obtained by deleting ith row and jth column
C. If A=[1657], then A is Skew-symmetric matrix
D. If A=[1425], then (A+A′) is Symmetric matrix
