Answer:
C. free verse
Step-by-step explanation:
Free verse poems are poems where verses have no metric, are verses introduced by modernism and are not based on predefined criteria, but on decisions that the poet makes intuitively or norms created by him. An example is Walt Whitman's "Long, Too Long America" poem, which has neither metric nor rhyme.
Apesar de poderem possuir rimas, a maioria dos poemas de verso livre não tem.
