I would say C. everyday speech. a free verse poem doesn't have a rhythm. And it doesnt have to rhyme.. so if it doesnt have a rhythm it cant be rhythmic rap. folk song generally rhyme to make them more memorable.. and the same with regular music.. plus, both folk songs and music have a rhythm.. :) hope this helps. let me know if i am wrong.
you can look it up i found a bunch of answers to it if you just look up the comparison for both of those also i recommend writing down all of the commandments and everything and using them and see what they have in common
