Answer:
C. A pipe
Explanation:
Based on the context clues, that is to say, by only looking at the surrounding information of the word "brier", we can infer that this word refers to "pipe", because before Rainsford announced that he was going to smoke a pipe. The next thing that happens is that he is reclining in a steamer chair and "puffed on his favorite brier." Furthermore, from all the choices there is only one thing that can be puffed on or be blown: a pipe.
