Answer:
C. (Aerophone)
Step-by-step explanation:
"A" can be written off because a chordophone is an instrument that has (a) string(s) stretched between two points.
"B" is also false because an idiophone does not require airflow, vibrates when hit or moved, and does not have strings. Eg, a gong, rattle, or bell.
C may be correct because an aerophone is just a wind instrument.
"D" is incorrect because a membranophone produces sound primarily by way of a vibrating stretched membrane. This is mostly drums, but also includes kazoos.
