Final answer:
Elie Wiesel felt 'pleased and frightened' during his Nobel Peace Prize acceptance speech, corresponding to option B, as he was grateful for the honor but overwhelmed by the continued responsibility.
Step-by-step explanation:
The question refers to Elie Wiesel's emotions during his acceptance speech for the Nobel Peace Prize. However, there seems to be a confusion with Malala Yousafzai mentioned in the reference, indicating a possible error, as she and Elie Wiesel are different individuals who both have received a Nobel Peace Prize.
For Elie Wiesel's speech, the correct emotions he described feeling were pleased and frightened, which corresponds to option B. In his speech, Wiesel conveyed his gratitude for the honor, thus feeling pleased, but also expressed a sense of overwhelming responsibility and fear, reflecting the emotion of being frightened, due to the weight of the task ahead of him to continue campaigning for peace and human rights after surviving the Holocaust.
