Property and casualty policies generally exclude losses due to which hazard?

• A. Flood
• B. Nuclear hazard
• C. Vandalism
• D. Collision

Answer: (B)

Property and casualty policies are built to cover common, manageable risks, while excluding hazards that are too unpredictable or catastrophic to price in a standard policy. The nuclear hazard exclusion is built into these policies because events involving nuclear reactions, radiation, or radioactive contamination can cause vast, long‑lasting damage and environmental cleanup costs that are nearly impossible to price and insure fairly. This is why standard P&C forms omit coverage for nuclear risk, pushing those losses into specialized coverages or government programs. Vandalism and collision are typically covered under these policies, and flood is usually excluded too but can be insured separately through flood programs; the key point is that nuclear hazard is the broad, fundamental exclusion among these options.
