Alarm notification can be a combination of which three things?

• A. Visual, audible, and electronic
• B. Audible, tactile, and textual
• C. Mechanical, electrical, and software
• D. Physical, digital, and wireless

Answer: (A)

Alarm notification is about how alerts reach people so they notice and respond. The best combination is visual, audible, and electronic. Visual alerts use lights or on-screen warnings, which help if someone can’t hear the alert or is in a loud environment. Audible alerts rely on sound to grab attention even when a display isn’t being watched. Electronic alerts involve digital signaling and automated messages that can trigger other devices or push notifications to monitors or mobile devices. Together, these modalities cover different ways people perceive warnings and work across various settings, increasing the chances that someone will notice and act. Other groupings don’t capture the common ways alarms are delivered, focusing on components or broader terms that don’t describe how the alert is actually perceived.
