Correct Answer: Simple pendulum motion.

Solution : The correct option is Simple Pendulum motion .

Simple harmonic motion is exemplified by pendulum motion. Simple harmonic motion happens when an item is subjected to a restoring force that is proportional to its displacement from a fixed point.
The restoring force in the case of a simple pendulum is provided by gravity. Gravity tries to reposition a pendulum when it is moved from its equilibrium position, which is the vertical hanging position. A sinusoidal motion results from this.
