The use of lie detectors is based on the assumption that lying produces emotional reactions in an individual that, in turn, create unconscious physiological responses.
(A) that, in turn, create unconscious physiological responses
(B) that creates unconscious physiological responses in turn
(C) creating, in turn, unconscious physiological responses
(D) to create, in turn, physiological responses that are unconscious
(E) who creates unconscious physiological responses in turn
题目分析：A中的that指的应该是reactions，是个复数，不能用creates，干掉B和E。C用进行时表示伴随，可是这句话强调的意思create不应是一个伴随状态，杀。D还用that are unconscious，明明直接修饰就可以说明白，用这个定语从句干什么，选A。
