Answer:
Anxious.
Step-by-step explanation:
The novel "Does My Head Look Big In This?" by Randa Abdel-Fattah tells the story of a young Australian Muslim girl who chose to wear a hijab in her elite Melbourne school. The change in her appearance amidst her friends and surroundings leads her to a lot of changes not only physically but even emotionally.
In the given excerpt, the tone used is more of an anxious one. The declaration "Who gives a da mn about Adam?" shows the indifferent feeling of the speaker while at the same time, anxious about what Adam and the other students will think of her.
Thus, the correct answer is anxious.
