What type of organization solicits insurance only to its members?

A fraternal benefit society is a specific type of organization that offers insurance products and services exclusively to its members, who usually share a common bond, such as nationality, religion, or professional affiliation. These societies not only provide insurance benefits but also promote social and charitable activities among their members. This characteristic of focusing solely on members distinguishes them from other entities in the insurance industry.

In contrast, a mutual insurance company, while also serving policyholders as its members, typically engages in a broader range of insurance operations and may include non-members in their offerings. An insurer generally refers to any entity that provides insurance coverage, which can encompass a variety of organizations, not limited to member-based models. A brokerage firm, on the other hand, acts as an intermediary between insurance buyers and insurers, and does not provide insurance directly to its customers. Thus, the unique focus of a fraternal benefit society on member-specific insurance offerings is what makes it the correct answer in this context.
