Explanation
Option A is correct because an information radiator is any large, highly visible display that passively broadcasts project status to anyone in the vicinity - no active query required. The traffic light fits perfectly: it radiates build health to the entire team at a glance.
Option B (Osmotic communication) refers to background awareness gained by overhearing conversations in a shared workspace - it's about spoken information absorbed incidentally, not a visual display device.
Option C (Triangulation) is a validation technique where you cross-check results using multiple independent methods or sources to increase confidence - unrelated to broadcasting status.
Memory tip: Think of an information radiator like a space heater - it emits information outward continuously, warming the whole room (team) without anyone having to ask for it. If it's big, visible, and always on, it's radiating.
