In what sense is Petrarch insincere in Sonnet 18 (sonnet inside)?a. Through professing his desire to be alone, he really craves the attention of...

If those four are your options, I would have to go with
C.  It is the only one that makes sense.

To me, what the
poem is saying is basically "you are so wonderful and beautful that I can't even manage
to write a poem about or talk about you -- you're just too good for
words."

If that's what he's talking about in this poem,
then only C really makes sense.  He's not really trying to get attention for himself so
it's not A.  He never claims his love is a secret so it's not B.  He doesn't praise
himself in the last lines so it's not D.

C kind of makes
sense because he does flatter her even though he can't actually describe
her.
