Which of these is NOT a common insurer provision?

The correct choice, indicating which option is not a common insurer provision, is abandonment. In the context of insurance, abandonment refers to the act of relinquishing ownership or responsibility for a damaged property. While it can be relevant in certain situations, such as when dealing with salvage, it is not a standard provision included in most insurance policies.

Common insurer provisions usually focus on how claims are handled and the rights and responsibilities of the insurer and the insured. Claim settlement options outline the methods by which claims can be resolved, and subrogation involves the insurer's right to pursue recoveries from third parties after compensating the insured. Salvage relates to the insurer’s right to take possession of damaged property to recover some cost. These provisions directly impact the claims process and the management of financial risk in insurance contracts, whereas abandonment does not typically constitute a defined right or responsibility in the context of policy terms.
