Which statements are true regarding a professional liability policy?

A professional liability policy is designed to protect professionals against claims of negligence, errors, or omissions in the services they provide. The Declaration Page is a key component of the policy, as it outlines the specific services covered by the policy, often identifying the profession and the nature of the work performed. This ensures clarity around what activities are protected in the event of a claim.

Additionally, under a professional liability policy, an Application (often referred to as “App”) is a critical piece that is reviewed by the insurer to assess risk before the policy is issued. It typically contains information about the applicant's qualifications, services provided, and loss history, and becomes a part of the policy. In terms of claims, the plaintiff is often a client, as these policies are meant to protect professionals from their clients’ claims regarding the professional services rendered.

Since both elements regarding the Declaration Page and the Application being part of the policy are accurate, the choice indicating that all statements are true is indeed the most complete and correct response.
