1 answer

The correct answer is:

B. endocrine system and nervous system

During a stressful situation, the nervous system activates the "fight or flight" response, which includes increased heart rate and pupil dilation. This response is also linked to the endocrine system, which releases stress hormones like adrenaline (epinephrine) that further enhance these physiological changes.
