Find the value of a parameter \( a\in\mathbb{R} \) so that the point \( B=[1;4;5] \) lies on the straight line \( p \) defined by the parametric equations \[\begin{aligned}p\colon x&=-1+m,\\ y&=2+am,\\ z&=3+m;\ m\in\mathbb{R}. \end{aligned}\]
\( a=1 \)
\( a=-1 \)
\( a=2 \)
no such value of \( a \) exists
