What type of insurance is not solely offered by a risk retention group?

The most accurate choice is health insurance, which is not solely offered by a risk retention group. Risk retention groups primarily provide liability insurance to their members, who are typically businesses or professionals in similar fields. The focus of these groups is on sharing liability risks among those involved, allowing them to band together to cover risks that may be too high for an individual entity to secure on its own.

While other types of insurance like property, auto, and liability can also be provided through various means, they are not primarily associated with the fundamental purpose of risk retention groups. Specifically, health insurance is more widely available through traditional insurance carriers and government programs, as it requires a different regulatory structure and risk pooling mechanism compared to liability coverage provided by risk retention groups. Therefore, health insurance stands out as an option that does not fall within the typical offerings of these specialized insurance entities.
