In the context of group insurance, what does it mean for a plan to be "contributory"?

In the context of group insurance, a plan being "contributory" means that employees are required to pay a portion of the premium. This arrangement contrasts with non-contributory plans, where the employer covers the entire premium cost without requiring any employee contribution.

In a contributory plan, financial commitment from the employees often leads to increased ownership and engagement in the insurance coverage. This can also affect participation levels; typically, everyone in the group must enroll to achieve full benefits.

The other options reflect different insurance arrangements or concepts. For example, an employer-only contribution suggests a non-contributory plan, while mentioning a smaller group doesn’t align directly with the definition of contributory insurance. Lastly, a plan that requires no employee involvement would also describe a non-contributory model. Thus, identifying B accurately captures the essence of what it means for a group insurance plan to be contributory.
