What is the correct sequence of events in emotional response according to the Cannon-Bard theory?

A) stimulus ? emotion ? physiological changes
B) stimulus ? physiological changes ? emotion
C) physiological changes ? stimulus ? emotion
D) stimulus ? emotion AND physiological changes (simultaneous)

Option D mentions that the stimulus leads to both emotions and physiological changes, happening simultaneously. This is the most accurate description of the association between the given stimulus and response. Option A and B mention emotions before physiological changes, which may not always be the case. Option C mentions physiological changes before the stimulus, which is not a plausible scenario. Hence, D is the best choice.
