Answer choice (C) says that people who do strenuous physical work are encouraged to use techniques to lessen the effect on their backs. Does that impact a relationship between office workers, office equipment, and back pain? It addresses a way to reduce back pain in other situations, but not in the situation in the stimulus.
Looking back at this question, I can see how answer choice C could support the conclusion. If the workers are "encouraged", then that encouragement had to come from somewhere (like upper management) and is analogous to optimization of chairs and computer screen angles.
This question is a bit of a doozy as it plays on an assumption already had: that people who lift heavy objects/physical work that places a lot of stress on the back have high numbers of injuries; but the correct answer choice E weakens by removing the incidence.
I narrowed my choices to C and E, and selected C.
