One of Cannon's Major Objections to the James-Lange Theory of Emotion

One of Cannon's major objections to the James-Lange theory of emotion was that:

A) physiological arousal alone does not lead to the perception of emotion.
B) the sympathetic nervous system was not given a more prominent role.
C) emotions have different intensities.
D) emotions are subjective experiences; therefore, no theory can be adequate in explaining them.
