Answer:
B. Indecisiveness
Explanation:
Ambivalence, as a general term, is defined as "having mixed feelings" about something. This sentence is no exception. On the one hand, she thinks it would be a good idea to visit her parents' country of birth, but on the other hand, she thinks it would be a bad idea.
Therefore, we can automatically certainty, as she thinks two very conflicting thoughts. Due to her worry of how difficult it would be to get back into the country, she is not necessarily entirely excited either. And while she fears the difficulty of getting back into the country, that is not the only emotion she feels.
