All of the following are typical exclusions in an insurance policy, EXCEPT:

Explosion is a typical covered peril in most standard insurance policies, particularly in homeowners and commercial policies. Exclusions are clauses that specify types of damages or events that are not covered by the insurance policy. While certain catastrophic events like nuclear hazards, earthquakes, and flooding are commonly excluded due to their high risk and potential for significant loss, explosions are often included as covered perils, provided they do not stem from excluded sources, such as nuclear incidents or acts of war.

The other options—nuclear hazards, earthquakes, and flooding—are frequently excluded because insurers find them too risky or unpredictable. For instance, flooding often requires separate policies, such as those from the National Flood Insurance Program, and earthquakes may have specific endorsements or may not be covered at all. Therefore, recognizing that explosions can typically be included in coverage, while the other events listed tend to be excluded, highlights the rationale behind this correct answer.
