P- Place these coordinate vectors into the columns fa matrix A. What can be said about the matrix A? O A. The matrix A forms a basis for R3 by the Invertible Matrix Theorem because all square matrices are row equivalent to I3. O B. The matrix A is invertible because it is row equivalent to I and therefore the row reduced columns of A forma basis for R3 by the Invertible Matrix Theorem. O C. The matrix A is invertible because it is row equivalent to I3 and therefore the null space of A, denoted Nul A, forms a basis for R3 by the Invertible Matrix Theorem. O D. The matrix A is invertible because it is row equivalent to l3 and therefore the original columns of A form a basis for R3 by the Invertible Matrix Theorem.
