Which statement about shakespeare's sonnets is true?
a. shakespeare invented the sonnet form.
b. shakespeare avoids figurative language in his sonnets.
c. shakespeare uses a specific rhyme scheme in his sonnets.
d. shakespeare takes petrarch's themes seriously.

The correct answer is C. Shakespeare uses a specific rhyme scheme in his sonnets. 

He uses the famous English Sonnet meter and rhyme, which was not his invention. He uses figurative language a lot and he does not take Petrarch's themes seriously, sometimes even writing in a negative manner which is somehow positive, such as: "My mistresses eyes are nothing like the sun" which is not something Petrarch would write.
