Answer:

Option C

Step-by-step explanation:

For the matrix A of order $n\times n$ to be invertible, its determinant must not be equal to zero, |A| $\neq$ 0, $A^{- 1}$ exists if- AC = CA = I, where I is identity matrix.

AB = 0, B = $A^{- 1}.0 = 0$

Thus, B = (0, 0, 0......., 0) is a unique solution

2. The non - homogeneous equation system with coefficient matrix A has a unique solution:

For an equation- AY = D

Y = $A^{- 1}.D$ is a unique solution

3. Every non homogeneous equation with coefficient matrix A is not consistent as:

For an equation- AY = D, has a solution.l Thus coefficient matrix is inconsistent whereas augmented matrix is.

4. Rank of matrix A = n, Thus the column space of A is $R^{n}$

5. Since, column space of A = $R^{n}$ , thus x→xA is one-to-one
