# If $\overrightarrow{u}, \overrightarrow{v}$ and $\overrightarrow{w}$ are three non-coplanar vectors, then $(\overrightarrow{u} + \overrightarrow{v} - \overrightarrow{w}) . [(\overrightarrow{u} - \overrightarrow{v}) \times (\overrightarrow{v} - \overrightarrow{w} ) ]$ equals :
( A ) $0$
( B ) $\overrightarrow{u}. \overrightarrow{v} \times \overrightarrow{w}$
( C ) $3\overrightarrow{u}. \overrightarrow{v} \times \overrightarrow{w}$
( D ) $\overrightarrow{u}. \overrightarrow{w} \times \overrightarrow{v}$
