Answer:

The correct option is B.

Explanation:

From the given graph it is clear the x-coordinate of the vector is 3 and y-coordinate of the vector is 4 in the coordinate plane.

The given vector can be defined as


A=\begin{bmatrix}3 & 4\end{bmatrix}

Translation vector is


B=\begin{bmatrix}0 & -1\\ 1 & 0\end{bmatrix}

We need to find the resulting vector,


AB=\begin{bmatrix}3 & 4\end{bmatrix}\cdot \begin{bmatrix}0 & -1\\ 1 & 0\end{bmatrix}


AB=\begin{bmatrix}3(0)+4(1) & 3(-1)+4(0)\end{bmatrix}


AB=\begin{bmatrix}4& -3\end{bmatrix}

Therefore the correct option is B.
