The correct option is: (A) away from the hole.
Assume that the solid body is symmetrical in shape, such that its center of mass coincides with its geometrical center. When a hole is cut from the body, the center of mass will shift away from the hole. It is important to note that the initial position of center of mass was dependent on the mass of the hole cut from the body, and when that mass is taken off from the body, the remaining mass governs its position, and tries to pull it near them and away from the hole.
