(C) To multiply a column matrix of order $3 	imes 1$ by a row matrix of order $1 	imes 3$,we perform matrix multiplication where each element of the resulting $3 	imes 3$ matrix is the product of the corresponding row element of the first matrix and column element of the second matrix.$\begin{bmatrix} 1 \ -1 \ 2 \end{bmatrix} \begin{bmatrix} 2 & 1 & -1 \end{bmatrix} = \begin{bmatrix} 1(2) & 1(1) & 1(-1) \ -1(2) & -1(1) & -1(-1) \ 2(2) & 2(1) & 2(-1) \end{bmatrix} = \begin{bmatrix} 2 & 1 & -1 \ -2 & -1 & 1 \ 4 & 2 & -2 \end{bmatrix}$.

$\begin{bmatrix} 1 \\ -1 \\ 2 \end{bmatrix} \begin{bmatrix} 2 & 1 & -1 \end{bmatrix} = $
