Final answer:
Guitar and violin are examples of chordophones, which are stringed instruments that produce sound through the vibration of strings.
Step-by-step explanation:
The answer to the question 'Which instrument listed below is an example of a chordophone?' with the options A) Trombone, B) Electric keyboard, C) Guitar, and D) Violin is C) Guitar and D) Violin. Chordophones are musical instruments where sound is produced by vibrating strings. So, both guitar and violin are correct examples of chordophones, as they are instruments that produce sound via the vibration of strings that are plucked, strummed, or bowed.
In the classification system used in ethnomusicology, there are four primary categories of musical instruments: Aerophones (wind instruments), Chordophones (stringed instruments), Membranophones (instruments with a membrane, like drums), and Idiophones (self-sounding instruments).
The guitar, as well as the violin, are classified as chordophones because they have strings that are the primary source of sound when played.
