Which condition in a commercial property policy could help cover the cost of damage from a gas explosion?

The Control of Property condition in a commercial property policy addresses the relationship between the insured parties and the property in question. This condition outlines how the insured must maintain and manage the property to prevent loss or damage from risks such as fire or explosions, including gas explosions. If the insured takes reasonable steps to control the use of gas and adhere to safety regulations, this condition supports the insurer's obligation to cover damages resulting from a gas explosion, provided other policy terms and conditions are met.

In a commercial context, this condition emphasizes that the insured's actions in managing the property can directly impact coverage. Thus, if damage occurs due to negligence in handling potentially hazardous materials like gas, the insurer may have grounds to deny a claim based on this condition. However, when proper safety protocols are followed, this condition serves to affirm coverage for related incidents, making it crucial for claim eligibility in situations involving gas explosions.

The other options provided do not directly relate to the question's focus on coverage for damage due to a gas explosion specifically. These conditions pertain to different aspects of policy management and claim processes, which are less relevant in determining coverage for explosive damage.
