The correct answer is:
$[\mathbf{a} \mathbf{b} \mathbf{c}]=0$
Vector $\mathbf{a}$ lie in the plane of vector $\mathbf{b}$ and $\mathbf{c}$.
$\therefore$ a,b, c are coplanar vectors.
Hence, a
$$
\begin{aligned}
(\mathbf{b} \times \mathbf{c}) & =0 \\
{[\mathbf{a} \mathbf{b} \mathbf{c}] } & =0
\end{aligned}
$$
$\therefore$ a,b, c are coplanar vectors.
Hence, a
$$
\begin{aligned}
(\mathbf{b} \times \mathbf{c}) & =0 \\
{[\mathbf{a} \mathbf{b} \mathbf{c}] } & =0
\end{aligned}
$$
