On using elementary column operations $C_2\times C_2-2C_1$ in the following matrix equation\[\begin{bmatrix}1 & 3\\2 & 4\end{bmatrix}=\begin{bmatrix}1 & 1\\0 & 1\end{bmatrix}\begin{bmatrix}3 & 1\\2 & 4\end{bmatrix}, \text{we have}\]

Question

\begin{array}{1 1}(A)\quad\begin{bmatrix}1 & -5\\0 & 4\end{bmatrix}=\begin{bmatrix}1 & 1\\2 & 2\end{bmatrix}\begin{bmatrix}3 & -5\\2 & 0\end{bmatrix}\\(B)\quad\begin{bmatrix}1 & -5\\0 & 4\end{bmatrix}=\begin{bmatrix}1 & 1\\0 & 1\end{bmatrix}\begin{bmatrix}3 & -5\\-0 & 2\end{bmatrix}\\(C)\quad\begin{bmatrix}1 & 5\\0 & 2\end{bmatrix}=\begin{bmatrix}1 & 3\\0 & 1\end{bmatrix}\begin{bmatrix}3 & 1\\2 & 4\end{bmatrix}\\(D)\quad\begin{bmatrix}1 & 5\\2 & 0\end{bmatrix}=\begin{bmatrix}1 & 1\\0 & 1\end{bmatrix}\begin{bmatrix}3 & -5\\2 & 0\end{bmatrix}\\\end{array}
