Which of the following is NOT a physical change associated with fear?

Calmness is the correct choice as it is not a physical change associated with fear. Fear is typically characterized by a range of physiological responses intended to prepare the body for a fight-or-flight reaction. These responses include increased heart rate (pounding heart), trembling, and nausea, all of which are physical manifestations of the body’s stress response. Calmness, on the other hand, suggests a state of relaxation or absence of stress, which contradicts the physiological effects typically observed in a fearful state. Therefore, identifying calmness as not being a physical response related to fear is accurate, as it reflects an emotional state contrary to the arousal and tension commonly elicited by fear.
