Using the label, what is the trade name of the medication? (No label provided; assuming Zestril from prior context.)

Choice A reason: Lisinopril is the generic name; trade names are branded, and this doesn’t fit the question’s focus on the manufacturer’s marketed title. Choice B reason: Zestril is the trade name for lisinopril; it’s trademarked by the manufacturer, aligning with the question’s request for the branded medication name. Choice C reason: Acetaminophen is a generic, not a trade name here; it’s unrelated to Zestril’s class (ACE inhibitor), making it an incorrect option. Choice D reason: Morphine is a generic opioid; it doesn’t match Zestril’s antihypertensive role or trade name status, ruling it out entirely.
