Margo,an inexperienced pilot,prepares for an emergency landing after her single-engine plane loses power.Margo's emotional arousal is likely to be accompanied by

A) decreased respiration.
B) pupil constriction.
C) increased blood sugar levels.
D) increased salivation.

In a high-stress situation like an emergency landing, Margo's body is likely to activate the fight or flight response, which releases stress hormones such as adrenaline and cortisol. One of the effects of these hormones is an increase in blood sugar levels, providing energy to deal with the stressful situation. Decreased respiration (A) and pupil constriction (B) are not typical responses to high emotional arousal, while increased salivation (D) may not be relevant in this particular situation.
