Answer
The planar vector fields satisfies by the $\bf{Plot (B)}$.
Work Step by Step
When we draw a vector field , we need to draw $F(P)$ as a vector based at a point (let us say a point) $P$. The domain of $F$ corresponds to the set of points $P$ for which $F(P)$ is defined.
This follows that $F(x,y,z)=\lt x,y,z \gt \quad \text{and} \quad F=x \ i+y \ j+z \ k$
Thus, when we draw a vector field of $F$ at any point the vector will be directed to $x \ i+y \ j+z \ k$ direction.
So, we interpret from the above discussion that the planar vector fields satisfies by the $\bf{Plot (B)}$.
