Hint - For solving this question firstly we should know about the concept of sound. We will gather all the knowledge (as required in this question) for sound. And hence with this information, we will be able to approach our answer.
Step-By-Step answer:
Sound is a form of energy which travels through in a form of mechanical waves. Sound is something that can be heard. Everything around us generates sound.
Sound is a mechanical wave. Mechanical wave is a disturbance that travels in three mediums that are solid, liquid and gases.
Let’s take some examples of the sound—Mechanical movement like clapping your hands or hitting a goal when hitting a goal which causes another molecule to vibrate and these vibrations of one molecule to another molecule help sound to travel.
Take another example -- when a bell rings it vibrates, which shows the bell itself flex inward and outward direction rapidly. When the bell moves outward it pushes the air particles and when the bell moves inward it pulls the air particles. This pull and push particle is a sound wave. The vibrating well is an original disturbance.
Hence the correct Option is C – The disturbance.
Note - First person to discover sound needs for a medium was Robert Boyle (1627-1691). We couldn’t hear sound in vacuum because there would not be any molecule present to vibrate. Sound needs medium to travel. Sound propagates in a three medium which is solid, liquid and gases.
