Under the commercial property coverage program, the basic causes of loss form insures against loss caused by:

The basic causes of loss form under the commercial property coverage program provides coverage for a limited range of perils. One of the perils specifically covered is sprinkler leakage, which includes damage caused by the accidental discharge of water from a sprinkler system. This coverage is essential for businesses that may rely on such systems for fire protection, as they could face significant damage if a sprinkler were to leak or malfunction.

In contrast, earthquake damage is not typically covered under the basic causes of loss form and would require additional coverage or a separate policy. Similarly, flood damage is excluded and necessitates specific flood insurance due to the high risk associated with flooding, which is considered a distinct peril. Breakage of glass is also not commonly included in the basic coverage, as it may fall under separate glass coverage policies. Thus, sprinkler leakage is the correct answer, highlighting the specialized nature of coverage provided by the basic causes of loss form in the context of commercial property insurance.
