Consider the following statements: I. det(A" B) =det (B" A) detC II. If A, B, C are square invertible matrices of the same size, then det(A" B-!CA-!) = det B III. If A and B are two 4 × 4 matrices such that AB = 0, then either A or B is a zero matrix IV. If the augmented matrix [A : b] of the linear system Ax = b is reduced to a reduced row echelon form, then the system is consistent V. For the matrix A, the equality A²? = A is satisfied only for A = I or A = 0 How many of the above statements must always be true? (i) 1 (ii) 2 (iii) 3 (iv) 4 (v) 5 Mark the correct answer in ois
