Which option is NOT produced by sympathetic activation?

Explanation:
Sympathetic activation readies the body for quick action. It raises heart rate and contractility, redirects blood toward the muscles and vital organs, and opens the airways to improve breathing. It also dilates the pupil by stimulating the radial muscle, allowing more light in. Pupillary constriction, however, is caused by parasympathetic activation, which tightens the pupil via the sphincter pupillae. So the effect not produced by sympathetic activation is pupillary constriction.
