Which statement correctly distinguishes Petrarchan from Shakespearean sonnet forms?

• A. Petrarchan consists of octave and sestet; Shakespearean consists of three quatrains and a couplet
• B. Petrarchan uses free verse only
• C. Shakespearean has no rhyme
• D. Both have identical structures

Answer: (A)

The main idea here is how the lines are organized in the two famous sonnet forms. A Petrarchan, or Italian, sonnet is split into an octave of eight lines and a sestet of six lines, with a common pattern around the octave (often ABBA ABBA) and a more variable sestet (like CDE CDE or CDC CDC). The turn in thought usually happens between the octave and the sestet. A Shakespearean, or English, sonnet uses three four-line units called quatrains plus a final two-line couplet, with a typical rhyme scheme ABAB CDCD EFEF GG. This structural difference—octave and sestet versus three quatrains and a couplet—is what clearly sets the two forms apart. The other statements don’t fit because Petrarchan and Shakespearean sonnets both use fixed verse and rhyme (so free verse is incorrect, and Shakespearean does rhyme), and they do not share identical structures.
