centripetal force directed at the center of the circle causes the marble to continue moving tangent to the circle.

c.
centrifugal force directed at the center of the circle causes the marble to continue moving parallel to the circle.

d.
centripetal force directed away from the center of the circle causes the marble to continue moving adjacent to the circle.
