Answer:
OA. It suggests he is very nervous as he approaches the podium.
Step-by-step explanation:
In the given scenario, the narrator mentions how Dawson was "rubbing the palms of his hands on his pant legs." This shows his nervousness because normally, rubbing of palms together is a sign of one's nervousness.
Moreover, the line "[H]e suddenly felt a strong sense of uneasiness emerge in the pit of his stomach" also reveals his 'nervous' state. He appeared uneasy, which is further clarified by the last line "Dawson could not hide his relief and elation."
Thus, the correct answer is option A.
