C) The composer may wish to use certain instruments to support other instruments; as the bass and harmony support the melody.
Usually, you have a lead guitar and another guitar player, a bass guitar, keyboard/synth, a drumset, and the vocalist. Old rock bands, like Earth Wind and Fire, used to have brass instruments (trumpet and trombone, occasionally saxophone[woodwind]) as part of the instrumentation. It depends on what era of rock you are looking for, but this is the most common instrumentation. Hope this helps! :)
