Consider a neutral conducting sphere. A positive point charge is placed outside the sphere. The net charge on the sphere is then,

negative and distributed uniformly over the surface of the sphere

negative and appears only at the point on the sphere closest to the point charge

negative and distributed non–uniformly over the entire surface of the sphere

zero
