One difference between the english sonnet and the italian sonnet is its
a. rhyme scheme.
b. subject matter.

d. theme.

The best answer here is A. The Italian sonnet follows the rhyme scheme ABBAABBA CDECDE (an octave and a sestet), while the English sonnet follows the rhyme scheme ABAB CDCD EFEF GG (three quatrains followed by a couplet). In the first pattern, the poet proposes a problem in the octave that he or she then resolves in the sestet. In the second pattern, the poet uses the final couplet to make a witty remark.
