Solution
The correct option is D Oscillatory motion
When a body moves forward and backward about its mean position with respect to time, it is known as oscillatory motion.
The swing is continuously moving forward and backward about its mean position, showing oscillatory motion. Hence, the child sitting on it depicts the same motion.
When a body moves about its own axis, it is known as rotational motion.
When a body moves in a circular path with respect to time, it is known as circular motion.
When a body moves in a straight line with respect to time, it is known as linear motion.
