    If \[\vec{a},\vec{b},\vec{c}\]are three non-coplanar vectors, then the vector equation\[\vec{r}=(1-p-q)\vec{a}+p\vec{b}+q\vec{c}\] represents a:

    A)  straight line

    B)                   plane

    C)                   plane passing through the origin

    D)                   sphere

    Correct Answer: B

    Solution :

    Since,\[\vec{a},\vec{b},\vec{c}\]are non-coplanar vectors, then the vector equation \[\vec{r}=(1-p-q)\vec{a}+p\vec{b}+q\vec{c}\]represents a plane.
