The correct answer is B. The first four lines of a verse that has the rhyme scheme abab
Step-by-step explanation:
In poetry, the word quatrain refers to a stanza or set of lines that include four lines. In the case of heroic quatrains, these quatrains have an abab rhyme scheme that implies in the stanza of four lines the final word of the first line rhymes with the final word of the third line and the final word of the second line rhymes with that one of the fourth or final line. This type of pattern was used by famous authors such including William Shakespeare. Therefore, a heroic quatrain refers to the first four lines of a verse or stanza that has the rhyme scheme abab.
