Choose the correct answer.
Suppose A is a 2 × 2 matrix, then if
1
Determinant |A| ≠ 0, the matrix is non singular and there is no linear dependence.
2
Determinant |A| ≠ 0, the matrix is singular and there is linear dependence.
3
Determinant |A| ≠ 0, the matrix is non- singular and its rank < 2.
4
Determinant |A| ≠ 0, the matrix is non - singular and there is linear dependence.
