Solution

The correct option is B Cannot be zero.
Resultant of vectors $\to A$ and $\to B$ lie in the same plane in which $\to A$ and $\to B$ lie. So, it makes some angle with vector $\to C$ which lies outside the plane. Hence, the resultant of these vectors cannot be zero.

Two vectors →A and →B lie in a plane, another vector →C lies outside this plane, then the resultant of these three vectors i.e.→A+→B+→C

The correct option is B Cannot be zero.Resultant of vectors →A and →B lie in the same plane in which →A and →B lie. So, it makes some angle with vector →C which lies outside the plane. Hence, the resultant of these vectors cannot be zero.
