Which of the following cannot qualify as a group for the purpose of purchasing group health insurance?

For a group to qualify for the purpose of purchasing group health insurance, it generally must meet certain criteria set forth by insurance regulations. A group typically must be comprised of a sufficient number of members, generally legally related in some capacity, and have a purpose that aligns with the collective purchase of health insurance.

In the case of an association with only 35 people, it often struggles to meet the criteria required for group underwriting. Associations or groups typically need to demonstrate an ongoing relationship and legitimacy with a common interest, along with a larger membership base to be considered viable for group health insurance. Many insurers look for a minimum number of employees or members to reduce adverse selection and ensure the group's sustainability. A labor union, multiple employer trust, or a larger employer group usually have a defined structure and purpose that fulfills these requirements, differentiating them from smaller or less structured associations.

This context highlights why the association of 35 people may not qualify compared to the other listed groups, which are more likely to fit the definition of a legitimate and insurable group under existing laws.
