Solution

The correct option is B x component at point C is along positive x-axis
Electric field $E_{x} = - \frac{d V}{d x}$ . So for negative slope, field will be directed along positive x. Thus x component at point A is towards negative x-axis and x component at point C is along positive x-axis and at point B, x-component of field will be minimum.
