Young Goodman Brown shows disbelief and astonishment at his companion's relaxed demeanor about dark historical events, indicating that option D. None of the above is the correct answer. The correct answer is option D.
From lines 8-9, readers can infer that Young Goodman Brown is in a state of disbelief and astonishment at his companion's nonchalance considering the serious and dark past actions the companion is revealing. The companion mentions their familiarity with Goodman Brown's ancestors and their shared cruel deeds, which seem to shock Goodman Brown. His reaction of calling out 'Can this be so?' with a 'stare of amazement' suggests that he is both shocked and in disbelief about the true nature of the people he has looked up to and the company he is currently keeping.
Therefore, the correct answer to the student's question is D. None of the above, since the text does not indicate that Goodman Brown knows who the companion is, nor that he is happy or annoyed to see him. Instead, his reaction is more complex, rooted in confusion and a paradigm shift regarding his perception of morality in his community.
Therefore, option D is correct.
