Given points \( A=[-4,1,4] \) and \( B=[4,-3,0] \), determine which of the following parametric equations does not define the ray \( AB \).
$\begin{aligned}
\mapsto AB\colon x&=-4+8t, \\
y&=1-4t, \\
z&=4-4t,\ t\in(-\infty,0]
\end{aligned}$
$\begin{aligned}
\mapsto AB\colon x&=-4+8t, \\
y&=1-4t, \\
z&=4-4t,\ t\in[0,\infty)
\end{aligned}$
$\begin{aligned}
\mapsto AB\colon x&=-4+2t, \\
y&=1-t, \\
z&=4-t,\ t\in[0,\infty)
\end{aligned}$
$\begin{aligned}
\mapsto AB\colon x&=-4-8t, \\
y&=1+4t, \\
z&=4+4t,\ t\in(-\infty,0]
\end{aligned}$
