Subrogationallows an insurer that has indemnified an insured to pursue recovery from the partylegally responsiblefor the loss. It prevents the insured from collecting twice and shifts the financial burden back to the negligent third party. Subrogation is a fundamental principle tied to indemnity.
Option A describes insurer action in fraud cases-not subrogation.
Option B is incorrect; deductibles are always retained by the insured, not reimbursed later.
Option C describes a release or waiver, not subrogation.
Thus, the correct definition isD.
