Answer 1

The correct option is C

Vibration

The explanation of the correct option:

In the case of option C:

1. Vibrational motion occurs when a body moves back and forth about its mean position.
2. Vibratory motion is defined as anything that moves back and forth, upward and downwards, pulsates, spins, or vibrates.
3. Pendulums, swings, and metronomes are examples of vibratory motion.

The explanation of the incorrect options:

1. In the case of option A, a disturbance in which energy is transferred from one location to another is called waves.
2. In the case of option B, the amplitude is the largest displacement of a wave on either extreme of its mean location.

Therefore, option C is the correct choice.
