Explanation:

Centripetal force is defined as the force that acts on an object moving in a circular path and is directed toward the center of the circle. For a ball on a string being spun in a circle, the centripetal force (provided by the tension in the string) pulls the ball toward the center of the circular path. Option A is incorrect as it's not about being perpendicular to the person. Option B is incorrect as it's not parallel to the person. Option C is incorrect because "outward - seeking" describes centrifugal force (a fictitious force in the non - inertial frame), while centripetal force is center - seeking.

Answer:

D. center - seeking.
