Under the concept of salvage, the insurer is responsible to:

The concept of salvage in insurance refers to the recovery of property that an insurer can sell or salvage after paying a claim for a loss. When an insured property is damaged, the insurer has a responsibility to minimize further damage to that property. This duty includes contributing towards expenses that are incurred in protecting the property from additional harm after a loss has occurred.

In the context of this question, the correct choice highlights the insurer's obligation to assist in mitigating further losses, which is an important aspect of managing claims effectively. This responsibility reflects a proactive approach in preserving what may still have value, rather than solely focusing on the financial settlements or increasing coverage, which are not part of the duty outlined under the salvage concept. Thus, the insurer assisting with expenses to protect property is essential for both the insured's interest and the insurer's risk management practices.
