Why is it beneficial for a decision helper to be present during an enrollment call?

Having a decision helper present during an enrollment call is beneficial primarily because they can support the consumer in comprehending the complex information being presented. Enrollment calls often involve detailed explanations regarding plans, coverage options, benefits, and potential costs. A decision helper can clarify these points, ensuring that the consumer fully grasps the choices available and their implications. This understanding is crucial for making informed decisions regarding healthcare options, as it directly impacts the consumer's ability to select a plan that best suits their needs.

While it's true that decision helpers could also ask questions or potentially expedite the process, their primary role is to facilitate understanding, making choice C the most relevant and impactful benefit in this context.
