A Juanita le interesantes las obras de ese poeta.
A. parece
B. mole stan (that word is one but won't let me say it)
C. parecen
D. parezco

C. parecen

Explanation:

The sentence translates to "Juanita the works of that poet are interesting."

The only reasonable answer would be "thinks" no?

"le parecen" in Spanish means that, so parecen is your answer.

** I did also want to add that it's also parecen because it's referring to "las obras" which is plural. That means that the verb (parecen) must be plural as well.
