Physical responses to stress can include which of the following?

• A. Slower breathing, relaxed muscles, narrowing of pupils
• B. Faster breathing, tense muscles, widening of pupils
• C. Headache
• D. Decreased heart rate and sweating

Answer: (B)

The main concept here is how the body’s fight-or-flight response shapes physical reactions to stress. When stress hits, the sympathetic nervous system activates to prepare for quick action. This brings faster breathing to supply more oxygen, tensed muscles for ready movement, and pupil dilation to improve vision and awareness. That combination—faster breathing, tense muscles, and widened pupils—best matches the classic immediate responses you’d expect in a stress situation.

Slower breathing and relaxed muscles point to a relaxed state, which isn’t how the body responds to acute stress. Pupil constriction would be opposite to the dilated pupils seen in this heightened state. Headache can occur with stress but isn’t a defining immediate response like the three listed. Decreased heart rate contradicts the typical stress pattern, where heart rate usually increases and sweating often occurs.
