Answer 1

Answer: option D) sound being created in music instruments

Step-by-step explanation:

Resonance occurs when an object close in contact to a vibrating body begins to vibrate at the same frequency of the vibrating body.

Usually each object has a THRESHOLD frequency which must be equaled or exceeded before it is set into vibration.

Therefore, this is the PRINCIPLE behind MELODY i.e how sound is being created in music instruments.
