Final answer:
Without exact details of Roisa's decision in 'Awake', we extrapolate from similar character experiences that Roisa likely appreciates her time with the faeries but wishes to return to the human world.
Step-by-step explanation:
The decision Roisa makes at the end of 'Awake' is not explicitly detailed in the excerpts provided, so making a definitive statement about her decision is challenging without further context. However, it seems that Roisa's situation is comparable to the characters who experience a conflict between the allure of the faeries or the mystical world, and the pull of the familiar human world. In light of the information given, the closest match to describe Roisa's decision, based on a synthesis of experiences from the characters presented, would likely be that she appreciates the time she spent with the faeries, but she wishes to return to the human world (Option C). Characters like Sylvia found comfort in nature, akin to faeries' allure, while others, despite temptations or enchantments, recognized the ties or duties they have in the human world, indicating a complexity in their decisions that mirrors the heart of Roisa's dilemma as presented in the question.
