What is the typical onset and duration for sublingual nitroglycerin?

Explanation:
Sublingual nitroglycerin works quickly because it is absorbed directly through the mouth’s mucous membrane into the bloodstream, bypassing the liver’s first-pass metabolism. This fast absorption produces relief from angina in a short time. The typical onset is about 1–3 minutes, and the effects last around 20–30 minutes. That combination best matches rapid relief without an overly long duration, which is why this option is correct.
