• C. They mark warranty areas.
• D. They indicate alternative routes.

Answer: (A)

Safety signage like "Do Not Cross" and "Caution: Gap" is all about communicating hazards and where it’s not safe to go. These signs clearly mark boundaries that protect people from injury — for example, showing that crossing into a restricted or dangerous zone could lead to harm, or warning of a drop or gap that could cause a fall. The goal is to guide behavior so you stay in safe areas and proceed with extra care where needed. They’re meant for everyone who might be in the vicinity, not just staff. They aren’t about warranties or indicating alternative routes; they’re about preventing accidents by signaling hazards and safe boundaries.
