Final answer:
Blanket health insurance covers a group of people who may be exposed to the same risks, offering collective coverage without listing individuals by name in the policy.
Step-by-step explanation:
Among the options given, the correct statement regarding blanket health insurance is that it covers a group of people who may be exposed to the same risks. This type of insurance is designed to protect all the members of a specified group when they are exposed to the same risk, without naming the individuals in the policy. This is common in situations like travel for a sports team or employees working in a hazardous job. With blanket health insurance, the benefits do not change as the group changes, and members do not need to be part of an association. Instead, all individuals under the policy are automatically covered equally.
