Answer: The right answer is the C) Olivia ha estudiado mucho para la clase.
Explanation: Just to elaborate a little on the answer, it can be added that the present perfect in Spanish, as it does in English, combines the present tense of the verb <em>haber</em> (to have) and the participle of another verb (eaten/comido, said/dicho, and so on). The participle of the verb <em>estudiar</em> is <em>estudiado</em>, so options A and C are incorrect. Option D translates as "she is going to study," and that is not the present perfect, but the future.
