Answer:
C. Bagpipes
What are Bagpipes?
Bagpipes are a traditional Scottish instrument that consists of two or more single- or double-reed pipes, set in motion by wind fed by arm pressure on an animal-skin (or rubberized-cloth) bag. The pipes are held in wooden sockets (stocks) tied into the bag, which is inflated either by the mouth (through a blowpipe with a leather nonreturn valve) or by bellows strapped to the body.
