Anaphylaxis usually progresses to life-threatening status within which time frame?

Explanation:
Anaphylaxis is a rapidly evolving, life-threatening allergic reaction. After exposure, symptoms can escalate quickly, typically reaching a life‑threatening stage within minutes—usually within 30 minutes. This rapid window is why the description “quickly, within 30 minutes” best fits the usual course. While some reactions may begin very quickly, the standard framing emphasizes onset within half an hour. Options implying slow progression over 30 minutes or hours don’t describe the common pattern (though a biphasic reaction can occur later after initial stabilization).
