But some of her co-workers have claimed that the extra boost of caffeine has helped them focus on their work.What does the placebo effect mean in this specific situation? a.) The benefit is the result of the "control" (coffee, although decaffeinated) and not an effect of the "active ingredient" (caffeine). b.) The benefit is the result of the fact that the "treatment" (coffee, although decaffeinated) contains another "active ingredient" besides caffeine. c.) The benefit is due to the fact that the co-workers are given a "treatment" (coffee, although decaffeinated) and not an effect of the "active ingredient" (caffeine). d.) The co-workers get a benefit from the "treatment" (coffee, although decaffeinated) since they also drink coffee at the coffee shop across the street during breaks.arrow_forward
