Given points \( A=[-2;5;1] \) and \( B=[3;-1;2] \), determine which of the following parametric equations defines the ray \( AB \).
$\begin{aligned}
\mapsto AB\colon x&=3+5t, \\
y&=-1-6t, \\
z&=2+t;\ t\in [ -1;\infty)
\end{aligned}$
$\begin{aligned}
\mapsto AB\colon x&=-2+5t, \\
y&=5-6t, \\
z&=1+t;\ t\in(-\infty;1]
\end{aligned}$
$\begin{aligned}
\mapsto AB\colon x&=3-5t, \\
y&=-1+6t, \\
z&=2-t;\ t\in(-\infty;0]
\end{aligned}$
$\begin{aligned}
\mapsto AB\colon x&=-2-5t, \\
y&=5+6t, \\
z&=1-t;\ t\in [ 0;\infty)
\end{aligned}$
