Explanation

Life-Critical Applications (D) is the correct term for systems whose failure could directly harm or kill people - think hospital patient monitoring, air traffic control, or nuclear plant management. These require the highest availability standards because downtime isn't just a business problem; it's a safety emergency.

Why the distractors are wrong:

• A (Mission-Critical): Covers applications essential to core organizational operations (e.g., a bank's transaction system) - disruption causes major business loss, but not necessarily physical harm.
• B (Team-Critical): Not a standard industry classification; it's a made-up distractor.
• C (Business-Critical): Refers to applications vital to business continuity and revenue, but again, failure affects finances and operations - not human lives directly.

Memory tip: Think "Life-Critical = Lives at stake." The word "life" literally signals health and safety. When you see "health and safety" in an availability question, map it to "life."
