Abigail Lasin · Accepted Answer

Final Answer : B, Explanation :  The pretest behaviors described, such as an increased respiration rate and heartbeat, sweating, and shaking, all indicate activation of the sympathetic nervous system, which prepares the body for fight or flight responses in potentially stressful situations. After the exam is completed, the body returns to its normal state through activation of the parasympathetic nervous system, which promotes relaxation and recovery. Therefore, the best choice is B.
