Answer:
c. stanza
Step-by-step explanation:
A characteristic unique in poetry is its structure which is made up of stanzas. Stanzas are group of lines arranged together in a poem, and that are usually separated from other stanzas by a blank line.
A feature of stanzas is that they have both rhyme and structure schemes: while the former is the repetition of similar sounds in the final word of two or more lines, the latter refers to the pattern of stressed and unstressed syllables in a line of poetry.
