which outcome will not be a result of the stress response?

The outcome that will not be a result of the stress response is pupils narrowing. Stress response typically causes physiological changes like quickened breathing, muscle tension, raised blood pressure, and pupils dilating (not narrowing) as part of the "fight-or-flight" response. Pupils dilate to allow more light in for better vision under stress, so narrowing pupils would not be consistent with this response.
