• A. Safe to traverse
• B. Hazardous nature
• C. Stability
• D. Visibility

Answer: (B)

Rotten ice’s defining trait is its hazardous nature. It can fail without warning and is very difficult to operate on because the ice is decayed and honeycombed, with voids that undermine strength. This makes the ice unpredictable and dangerous for rescuers and equipment, since even light loading or movement can cause a sudden break. The danger isn’t about how visible the ice appears or whether it looks solid on the surface; it’s about the unreliability of its strength. That’s why describing rotten ice as hazardous best captures the risk and behavior you must plan for in ice rescue operations.
