Sentence Correction

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
(8) 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

OA is A. Lets discuss only A and the modified version of E below.
If E is modified to read "who, in turn, creates unconscious physiological responses".

I chose E, and found that it was the wrong choice. OG says 'who' is wrong as 'that' refers to reactions.
But what if the individual creates unconscious physiological responses.. wouldn't he be able to ?

So would the modified version of E be correct and better than A.
