Which symbol would indicate a load is dangerous when wet?

Explanation:
The key idea here is recognizing a sign that warns about moisture-reactive hazards. A blue background with a flame is used to indicate materials that become dangerous when they come into contact with water. The flame symbol communicates that moisture can cause flammable gas to be released or ignite, so special care is needed to keep the load dry and away from water. Other signs shown point to different hazards: a green symbol with a canister suggests a gas container or pressurized gas, a black-and-white symbol with a test tube points to a chemical hazard (often corrosive or toxic), and a yellow-and-white general hazard logo signals a broad warning. None of these specifically warn that the material is dangerous when wet, which is why the blue-with-flame sign is the correct indicator in this context.
