Answer:
d. He is delicate and gentle
Step-by-step explanation:
What the reader can infer about Maniac from Paragraph 6 is that he is delicate and gentle.
This is true because we are told in paragraph 6 that Maniac poke, tug and pick at the knot. Also, the paragraph reveals that he is one that never yanked or pulled big but he was only touching and grazing with his fingertips. These descriptions actually depict that Maniac is delicate and gentle.
