C-prazosin is an alpha1 blocker. NE will hit alpha 2 producing vasoconstriction and NE's reflex bradycardia response will be blunted by scopolamine. I'm not sure how angiotensin will be blocked by scopolamine...?

As I remember angiotensin beside the obvious vasoconstriction will cause a reflex bradycardia blocked by scopolamine.{i think it helps to know Norepi backward and forward}

I'm really confused how angiotensin is the answer...it even a drug? whats the exact mechanism of action..??? plus, it's reflex bradycardia seems like it would be blocked by scoplamine since that acts by a different mechanism

AT II acting on ATII receptors has nothing to fo with Alpha1 blocker Prazosin and Scopolamine which is a Muscarinic blocker can prevent reflex tachycardia.

Prozosin cannot block the vasoconstriction caused by angiotensin.
Thus, I'll go w/ C.
