Answer 1

C. Cello playing music at a concert

Answer 2

c.a cello playing music at a concert

Step-by-step explanation:

Vibration motion is produced when the strings of a cello are plucked by a musician. Vibration in a string produces a wave, and the vibrating string produces a sound of a certain frequency. Most often we see the tension of a string gets adjusted, and thus help to create a sound or music of a definite frequency.
