Dados los puntos \( A=[-2,5,1] \) y \( B=[3,-1,2] \). Determina cuál de las siguientes ecuaciones paramétricas define la semirecta \( AB \).
$\begin{aligned}
\mapsto AB\colon x&=3+5t, \\
y&=-1-6t, \\
z&=2+t,\ t\in [ -1,\infty)
\end{aligned}$
$\begin{aligned}
\mapsto AB\colon x&=-2+5t, \\
y&=5-6t, \\
z&=1+t,\ t\in(-\infty,1]
\end{aligned}$
$\begin{aligned}
\mapsto AB\colon x&=3-5t, \\
y&=-1+6t, \\
z&=2-t,\ t\in(-\infty,0]
\end{aligned}$
$\begin{aligned}
\mapsto AB\colon x&=-2-5t, \\
y&=5+6t, \\
z&=1-t,\ t\in [ 0,\infty)
\end{aligned}$
