Which of the following correctly identifies a cause of loss that is NOT covered by standard policies?

Seepage of water is a cause of loss that is typically not covered by standard property policies, especially those pertaining to commercial properties. Standard policies often exclude damages resulting from gradual leaks or seepage, which can lead to issues like mold growth and structural damage over time. These exclusions are based on the understanding that such conditions usually result from maintenance neglect rather than a sudden event, making them the responsibility of the property owner to manage.

In contrast, causes of loss like fire damage, smoke damage, and explosion of steam are generally covered under standard commercial property insurance policies. These events are considered sudden and accidental, which aligns with the principle of providing coverage for unexpected and catastrophic incidents. As a result, property owners can typically expect their policies to provide financial protection against those specific types of damage.
