Identify which of the following systems of equations has infinitely many solutions.
\( \begin{aligned} \frac12x-3y&=12\\ -\frac{1}3x+2y&=-8 \end{aligned} \)
\( \begin{aligned} \frac13 x-2y&=12 \\ -\frac12 x+3y&=-16 \end{aligned} \)
\( \begin{aligned} \frac12 x+2y&=12 \\ -\frac13 x-3y&=-12 \end{aligned} \)
\( \begin{aligned} \frac12 x-y&=12 \\ -\frac23 x+4y&=-8\end{aligned} \)
