What involves reviewing and investigating the cause of an insurance claim?

The process of reviewing and investigating the cause of an insurance claim is best described by claim adjustment. Claim adjustment refers to the activities carried out by an insurance adjuster to determine the validity of a claim and the extent of the insurance company's liability. This involves collecting evidence, interviewing witnesses, and assessing damages to establish what is covered under the policy and the rightful compensation to the claimant.

In the context of the options provided, problem analysis generally refers to the method of identifying and understanding issues rather than specifically dealing with insurance claims. Risk assessment involves identifying and analyzing potential risks that could impact an organization or individual, and loss control relates to measures taken to prevent or reduce losses. While these concepts are essential in the broader context of insurance, they do not specifically capture the focused activities associated with investigating and reviewing insurance claims.
