The answer is: alliteration.
Alliteration is the occurrence of the same sound or letter at the beginning of contiguous or closely connected words.
In the example lines, each of them contain alliteration. For example:
Line 1264: marked, murdered, moved.
Line 1268: with, watcher, waiting.
Line 1269: wrenched, wrestled.
Line 1274: brought, hell-brute, broken, bowed.
Line 1288: hall, hard-honed.
Nervously
Unevenly
Tensed
Startled
Blankly maybe if you’re talking about something creepy’s emotional state.

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.
