Answer:
A couplet is the correct answer.
Explanation:
A Petrarchan sonnet has its own rhyme and structure, meaning that they are composed by two stanzas and octave (eight lines) and a sestet (six lines) or they may have three stanzas (two quatrains -four lines- and a sestet;) on the other hand, the English sonnet has fourteen lines with three quatrains (12 lines) and a couplet (two lines.)
