答案：B

解析：

Choice B is the best answer. Based on the passage's description of Mednick's predictions, it can be concluded that the graph's x-axis moves from close associations, like "chair," to more remote associations, like "food." The graph shows that creative people (those with flat associative hierarchies, according to Mednick) would be more likely than less creative people (those with steep associative hierarchies) to make a remote association during the task. The graph also shows that the word with the highest likelihood of retrieval for both groups of people would be "chair" -- a close association.
