Answer:
B. The xylophone, whose name comes from the Greek xylon, meaning “wood,” is a percussion instrument. The xylophone consists of a series of wooden bars that are struck with mallets to produce sounds
Step-by-step explanation:
This option is simplier than the original sentence because the complex structure "..... consisting of a series of wooden bars....." is replaced by a new and simplier sentence. This new sentence makes it clear that the subject of the verb " to consist" is "the xylophone ". In the original sentence the subject of the verb "to consist" is "percussion instrument" , thus "the xylophone" , but the reader has to link the synonymous expressions, first, and then link both words to consist. This is not the case in the simpler version.
