The electric potential in a region of two-dimensional space is given by the function \(V(x, y) = \alpha x^2 - \beta y^2\), where \(\alpha\) and \(\beta\) are positive constants. Which of the following correctly gives the electric field vector \(\vec{E}\) at a point \((x_0, y_0)\) located in the first quadrant (where \(x_0 > 0\) and \(y_0 > 0\)), and identifies the quadrant of the \(xy\)-plane toward which \(\vec{E}\) points?
