Answer:
d. He is delicate and gentle
Step-by-step explanation:
Option D is the correct answer. It is what the reader can infer about Maniac from paragraph 6.
The writer revealed that Maniac poked, tugged and picked at the knot. Also, the reader also discovers that Maniac doesn't pull big or yank. He only touches and grazes with his fingertips like some little bird.
The description of Maniac here shows that he is delicate and gentle.
