Identify which of the following systems of equations has infinitely many solutions.

\begin{aligned} \frac{1}{2} x - 3 y & = 12 \\ - \frac{1}{3} x + 2 y & = - 8 \end{aligned}

\begin{aligned} \frac{1}{3} x - 2 y & = 12 \\ - \frac{1}{2} x + 3 y & = - 16 \end{aligned}

\begin{aligned} \frac{1}{2} x + 2 y & = 12 \\ - \frac{1}{3} x - 3 y & = - 12 \end{aligned}

\begin{aligned} \frac{1}{2} x - y & = 12 \\ - \frac{2}{3} x + 4 y & = - 8 \end{aligned}
