Answer:
3. A porcupine.
Explanation:
From the file attached, the excerpt is from Chapter 8 of The Hatchet by Gary Paulsen where he describes how Brian was attacked in the middle of the night by a weird animal which he could not see in the darkness. From the narrative, the animal smelt of rot, it slithered and made a brushing sound towards his legs and he kicked out and threw a hatchet but missed.
His legs felt as if "a hundred needles have been driven into it" and he touched the group of needles that were stuck in his legs and discovered they were quils from a porcupine.
