For the given circuit, which one of the following is correct state equation?

1. $\dfrac{\mathrm{d} }{\mathrm{d} t}\begin{bmatrix} v\\ i \end{bmatrix}=\begin{bmatrix} -4 &4 \\ -2 & -4 \end{bmatrix}\begin{bmatrix} v\\ i \end{bmatrix}+\begin{bmatrix} 0 & 4\\ 4& 0 \end{bmatrix}\begin{bmatrix} i_{1}\\ i_{2} \end{bmatrix} \\$
2. $\dfrac{\mathrm{d} }{\mathrm{d} t}\begin{bmatrix} v\\ i \end{bmatrix}=\begin{bmatrix} -4 &-4 \\ -2 & 4 \end{bmatrix}\begin{bmatrix} v\\ i \end{bmatrix}+\begin{bmatrix} 4 & 4\\ 4& 0 \end{bmatrix}\begin{bmatrix} i_{1}\\ i_{2} \end{bmatrix} \\$
3. $\dfrac{\mathrm{d} }{\mathrm{d} t}\begin{bmatrix} v\\ i \end{bmatrix}=\begin{bmatrix} 4 &-4 \\ -2 & -4 \end{bmatrix}\begin{bmatrix} v\\ i \end{bmatrix}+\begin{bmatrix} 0& 4\\ 4& 4 \end{bmatrix}\begin{bmatrix} i_{1}\\ i_{2} \end{bmatrix} \\$
4. $\dfrac{\mathrm{d} }{\mathrm{d} t}\begin{bmatrix} v\\ i \end{bmatrix}=\begin{bmatrix} -4 &-4 \\ -2 & -4 \end{bmatrix}\begin{bmatrix} v\\ i \end{bmatrix}+\begin{bmatrix} 4& 0\\ 0& 4 \end{bmatrix}\begin{bmatrix} i_{1}\\ i_{2} \end{bmatrix} \\$
