Answer:
B. The mood is uplifting is the correct answer.
Step-by-step explanation:
In this case, the allusion refers to the story of Cinderella; even thought it is very sad (specially how she was treated by her step-sisters and step-mom) at the end everything changes when the prince finds her. In this case, the sentence refers to a particular, desperate situation but it changes at the end when it says no one else seemed to notice in reference to the prince and how he paid special attention to Cinderella when no one else cared, so B is the correct answer.
