Answer:

D. Catching a ball

Explanation: Purely rotational motion occurs if every particle in the body moves in a circle about a single line.

In a "Ferris wheel", forces are not balanced. Objects that have circular motion have something called “centripetal force”. Centripetal is a word meaning “centre seeking.” The centripetal force always points to the centre of the circle. Ferris wheel physics is directly related to centripetal acceleration.

Rotate the "merry-go-round" to change its angle or choose a constant angular velocity or angular acceleration. ... A circular motion requires a force, the so-called centripetal force, which is directed to the axis of rotation. This simplified model of a carousel demonstrates this force.

A "spinning top" has a rotatory motion because it spins (or rotates) with a certain angular acceleration about an axis passing through its center.
