Answer:
Option A
Step-by-step explanation:
The answer is option A or "Ode." A ode is a lyrical poem that was wrote for a certain subject such as racism or murder. It's not option B because rhymes are in a poem, it's not option C because a syllable is used to help pronounce words by using sounds, and it's not option D because theme is also the main idea and in this case the main idea of this poem would be to stop racism.
Hope this helps.
