What is a periodic motion ?

Periodic Motion is defined as the motion that is repeated after equal intervals of time. The same state of motion is repeated in specific intervals of time and the smallest interval will be the fundamental time period of the motion.

When the bob is displaced from equilibrium and then released, it begins its back and forth vibration about its fixed equilibrium position. The motion is regular and repeating, hence it is a periodic motion

while all other options are not periodic as they are not regular as well as repeating  and are irregular motion , hence non - periodic motion.

correct answer B) A pendulum swinging back and forth
