Final answer:
Bud's first impression of Herman E. Calloway in the novel is generally of an unapproachable and gruff individual, but without specific context from the text, a definitive answer to the multiple-choice question cannot be given.
Step-by-step explanation:
The student's question refers to Bud's first impression of Herman E. Calloway in the novel Bud, Not Buddy. Based on the limited information provided and without reference to the specific text or context within the novel, it is not possible to give a definitive answer to the multiple-choice question presented. However, in general, Bud's first impression of Herman E. Calloway in the story is that of an unapproachable and gruff individual, which aligns with choice (d). If this impression aligns with the specific segment mentioned, the answer would be (d) Bud thought he was unapproachable and gruff. It is important to note that without the specific context from the novel, this is a generalized deduction rather than a citation-based response.
