  yes, guys you're both right.

The correct answer is E. Benztropine is an agent indicated as an adjunct to treat all forms of parkinsonism. This agent is used primarily for its strong anticholinergic effects. Cholinergic antagonists competitively inhibit the activity of endogenous acetylcholine. A mnemonic to remember for the action of anticholinergic agents is that they have anti-SLUDG properties. They cause decreased Salivation, Lacrimation, Urination, Defecation, and Gastrointestinal motility. Therefore, they cause xerostomia (dry mouth) because of the lack of salivation. Other effects of anticholinergic medications are tachycardia, bronchodilation, mydriasis, blurred vision, and fever.

One would expect to see bradycardia (choice A), bronchoconstriction (choice B), lacrimation (choice C), and miosis (choice D) with cholinergic agonists.
