A unique feature of Nebivolol (Bystolic) is:

This is achieved through activation of endothelial nitric oxide synthase, leading to the release of nitric oxide which causes smooth muscle relaxation and vasodilation.

Option D is incorrect because Nebivolol was approved by the FDA in 2007, making it a relatively new beta blocker on the market.
