Which of the following could be a potential exclusion in a commercial property insurance policy?

A potential exclusion in a commercial property insurance policy is wear and tear. Commercial property insurance typically covers sudden and accidental damages to the insured property. However, regular maintenance issues or degradation of materials over time, commonly referred to as wear and tear, are usually not covered. Insurers consider wear and tear to be a result of normal usage and aging rather than an insurable peril. This distinction is crucial, as it ensures that policies focus on protecting policyholders against unexpected and covered risks instead of routine maintenance or deterioration.

Other types of damage, such as damage due to fire, flood, or theft, typically fall under covered perils or would require specific endorsements or additional coverage options. This is why wear and tear stands out as a clear exclusion in the context of commercial property insurance.
